nested itineraries and a shockingly low fare

I found myself with two short trips to make from London to the US within a little over a week (both for work, with work obligations in between in London, such that the travel couldn't be done crossing the Atlantic once).
Neither trip had a Saturday-night stay: one trip was LHR->IAD on a Monday, returning IAD->LHR the next day; the other was LHR->ABQ departing on the Sunday after the IAD->LHR flight, returning ABQ->LHR the following Wednesday.
As I'm sure many are aware, one possibility when one has two non-Saturday-stay trips like these is to use what are sometimes called "nested" itineraries: book one itinerary as the "outer" two flights (in this case, Monday LHR->IAD and Wednesday of the following week ABQ->LHR) and the other as the "inner" two flights (in this case, Tuesday IAD->LHR and the following Sunday ABQ->LHR). The advantage of booking this way is that we've turned two non-Saturday-stay itineraries (which usually cost upwards of GBP 1500 in Economy) into two Saturday-stay itineraries (which are typically available at the lowest available fare, often in a sale O fare basis).
Years ago (certainly around 2000), US domestic airfares were priced such that Saturday night-stay itineraries were significantly cheaper ("leisure" fares) than non-Saturday night-stay ("business," even in economy class) ones. But the US low-cost carriers like Southwest and JetBlue did away with those distinctions, always charging "leisure" fares. Eventually, the major US carriers had to follow suit to compete. But *before* that change, US carriers prohibited nested itineraries, because they saw them as "cheating" the airline out of the added revenue of non-Saturday stay itineraries. In fact, carriers searched reservation records for nested bookings under the same passenger name, and would often cancel tickets upon finding them.
I was concerned that VS might behave similarly, given that VS still charges way more for non-Saturday stay tickets than Saturday-stay ones. I was able to find FT threads (but only from a few years ago, interestingly) stating that BA prohibited nested itineraries. But I saw no evidence VS did. So I called VS and tried to book the above nested itineraries. The agent happily booked them for me. Wanting to avoid unexpected surprises, I then even pointed out to the agent that I'd just booked nested tickets, and asked if that was against Virgin policy. The agent said that this was absolutely fine by VS.
I'm curious: what are others' experiences with nested itineraries on Virgin in the recent past? Have others followed this practice without a problem, as well? Or have some been told by Virgin that such itineraries aren't allowed?
A final twist to this story:
I initially booked the above itineraries to LAX rather than ABQ, figuring I'd just book my own separate round-trip ticket on a US carrier between LAX and ABQ. I then realized that I wouldn't be able to inter-line my baggage if I made the trip on two separate tickets. So I called VS back within 24 hours of booking, and asked them to add hops from LAX->ABQ and ABQ->LAX to my itinerary.
They happily obliged, canceling my prior tickets and rebooking with the added hops. But the oddest (and most wonderful) thing happened. The "old" "inner" itinerary (IAD->LHR then LHR->LAX) had originally cost GBP 659. The "new" one (IAD->LHR then LHR->LAX->ABQ), however, came *down* in price to GBP *352.00*!! And what's more the fare bases were the same on the VS legs. Somehow, pricing the itinerary as a "through" ticket to ABQ drastically reduced the fare.
The agent was very amused, said he "wasn't going to argue with the system" since it had fared the itinerary this way. Result: a ticket with an extra leg I would have purchased separately for a little over *half* the price in the same classes of service, *and* I can inter-line my baggage!
There are occasionally *pleasant* surprises when setting up complex itineraries.
