Button can have an overpair, a set, an ace, a spade draw. I suppose he'll fold a pair between 6 and A. He'll fold the flush draw without the ace. He'll call with spades+ace, or a good ace, and of course a set. If he has spades you only have 6 outs, so that sucks.

Generally I don't see a need for this unless you think Button is weak/tight, but your only read is he's a little loose which usually means he'll call a little more than usual.
