Actually, it's as many jumps (minor hops) as you want, although I can't seem to stop losing forward momentum after a couple of throws. Still, it's quite handy that the only way Yoshi is helpless in midair now is if you blow it with Egg Roll.
As for attack strength, I don't know, I don't gauge knockback distance between games. It's kinda hard to when 99% of the time you're playing Super Sudden Death with all Bob-ombs. Yoshi's ground pound still seems strong enough to me, not AS strong as some of his A attacks, but I can live with that.
