Correct. It's the same idea as fitting a slightly larger tire using a body lift. If the arms were to hit the body, I'm pretty sure it would be the front lip of the fender. The BL moves that further away and allows one to cheat a bit on the clearances.
I recently installed an Antirock with 2" of spring lift plus an 1.25" BL. On mine, I still cut 3/4" off of each end of my links, totaling 1.5" just to be safe and to put the arms where they should be. This is why people say that a BL doesn't factor in to the installation, because a BL isn't needed if the links are an appropriate length.
