I would say that it doesn't give an advantage, but I did the same thing to him twice in a previous match (to prove a point to him and myself), and both serves were aces that he didn't even move to get...where he responded "whoah, great serve". You bet it was!!
I was able to hit so much more down on the ball and still have it land in, it was ridiculous. It probably felt to him like I put 10MPH more on my serve. I'm 6'1 and I imagined this is what it must be like to be 6'6 with your serve. Likewise, he's 5'5 or 5'6.
simple solution. As soon as the front foot slides inside the line, say Footfault before even he can get slide his back foot inside. This will let him know that he is definitely footfaulting even before he gets into the swing.
