steelers@ravens winning touchdown

[PackersFTW]

if you didn't see it, the steelers threw a pass and the guy caught it with both feet in the end zone, but the ball didn't cross the plane. is that a touchdown? i know when you go out of bounds, it's where the ball goes out, not where you do, but is it the same for the endzone? the announcers were saying yes that's how it works, but when the ref made the call (review under 2 minutes), he said "the receiver got both feet down with posession, touchdown". it doesn't make sense that he said that, because the question was did the ball cross the plane, not did he catch it. so basically he caught the ball with both feet in the end zone, but he was leaning forward as he caught it, so the ball never crossed the plane. touchdown or no?
