Can anyone explain the difference between these two penalties?

Penalty 1:

Penalty 1 (realtime)

Penalty 1 (replay)

All Blacks number 18 making the tackle lands on the wrong side of the ruck, impacting the French cleaners ability to clear out the jackler.

Result: Penalty against New Zealand for not rolling away and France get 3 points

Penalty 2

Penalty 2 (realtime)

Penalty 2 (replay)

France number 1 making the tackle lands on the wrong side of the ruck, impacting the All Blacks cleaners ability to clear out the jackler.

Result: Penalty against New Zealand for holding on and France get 3 points

To my mind these two plays look almost identical, but with completely different results. If anything, the All Blacks jackler effected the steal whereas the French jackler wasn't even on the ball?
