Not at all. You should use the card that gives you the most value for spend with that merchant. Of course you are going to take extra AA shopping portal miles on top of that. The two are independent.
For example if I was buying something that coded as travel, I would use my CSR for the 3 Chase pts, rather than 1 AA mile & LP, per dollar. That doesn't defeat the purpose of collecting the portal miles on top of that.
