I'm BMX-ignorant, but I think I just read in another thread something about 16t is the smallest freewheel you can fit on standard threading, and so the smaller freewheels use a different hub threading. Maybe the cogs are also smaller (Like, say, 3/32"?). It doesn't completely make sense as why would they all be 3/32" and why wouldn't the 1/8" chain work with them even if they were... But that could at least be why he thought of 15 as significantly different than 16.
