Is this right

Hello all,
Before I call and make an arse out of myself with the flying club.. does this seem right to you guys.. to me it seems wrong.
Booked a Y reward flight using the AMEX voucher to upgrade to PE, flying out to MCO then returning from LAX.
VAA Credit Card Rwd: Upgrade Econ.to Prem.Econ.rtn
Redemption Sale:Virgin Atlantic, LGW-MCO Econ rtn -42500
VAA Credit Card Rwd: Upgrade Econ.to Prem.Econ.rtn
Redemption Sale Fare: Virgin Atlantic LAX-LHR Economy -18750
Surely it should only be one credit card reward voucher used as they are good for a round trip and the LGW to MCO flight should be a single so not 42,500 miles but around the 18,000 mark like the LAX to LHR route?
Am I right or could I not be more wrong?
