I think I somewhat understand. He might have said something along this:
In Melee, as you full/short hop you can gently tap the the control stick up and press A for a uAir in one hop but in Brawl or whatever, it reads that gentle tap as a second jump thus using 2 jumps to perform a uAir?
Its my shot at it. I don't know if that's how it works in Brawl or not as I don't use the control stick for uAirs. I used to do that for Melee though.
