Agree with
@loh and we've had a similar experience. However, one time, my SA where our vacation home is made a comment that the credit card used for my DH's account should have his name on it instead of mine, in case the store gets audited by corporate. He actually showed me the part of the purchase confirmation where it shows the name on the card used. But the last time I was there, he (mistakenly) put our purchases under my account and I used the credit card with DH's name and he didn't say anything. So I don't think the system would reject a payment but it sounds like it's more of a policy in case they get audited. When we opened DH's account in a new store for us, the SA did say that everything had to be under his name, and we do use the card with his name on it when we make purchases.
Totally agree with
@smoothsailor regarding the 2 accounts and the same SA. If the SM realizes it's the same household, they may enforce the 2 QB/year anyways. My SA actually did say that H might move to 2 QB per household, instead of per profile/person, but not sure if that's actually going to happen. My DH and I have different accounts in different stores, not with the same SA. It was originally because my prior home store had a SM who was militant about not shopping anywhere else so I opened an account for DH at a different store so my purchases would not show up under my profile. But when you have 2 accounts, you also have to build the purchase profile for each and it can get complicated when they text you the same stuff to buy!! Or offer you the same non-quota bags (which has happened to me) and I had to turn one down. Or offer you a QB like 2 weeks apart and you don't want to say no so you buy both and bust your budget.
