why the difference?

[Nevadaref]

I don't follow the Fed's rationale for the difference in the penalty administration for these two plays:

1. A1 shoots and is fouled by B1, while the ball is on the ring A2 commits BI.
Penalty: No goal, A1 shoots 2 FTs with the lane spaces occupied. 6.7.9

2. A1 shoots and is fouled by B1, while the ball is one the ring A2 commits a foul against B2 under the basket. Team B is not in the bonus. The try is unsuccessful.
Penalty: No goal, award A1 2FTs with the lane cleared and give the ball to Team B OOB on the endline. 6.7.4 (slightly modified)

Both a violation and a foul carry the penalty of awarding the ball OOB to the opponents 7-4-1+6, so why the difference in how the game continues here?

Specifically, why not shoot with the lane cleared in #1 as well? It seems that we are failing to fully punish the violation by allowing Team A an attempt to rebound a miss on the final attempt.
What if the violation by A2 in play #1 had been for excessively swinging elbows? Does anyone feel that should change the ensuing FT administration?
