I remember discussing a play like this last year and I thought was outcome was TD in 1) and down at A1 in 2). If I recall correctly it was because in both situations the receiver didn't possess the ball until he contacted the ground. In situation 1) he falls to the ground after contact by B so you rule forward progress in the end zone but in situation 2) there is no forward progress because the receiver kept his feet and was tackled at the 1 yard line.

I think the example cited was forward progress near the line to gain.
