Elementary Timing Question

[ljudge]

This is kind of a timing-101 question but I'm going to ask any way. Having a brain malfunction this morning. There are two case questions that seem to conflict.

3.4.2D: K11 puts the ball from 4th and 10 situation. R1 catches the kick and returns 10 yards. During the down, but prior to the catch, K3 holds R2. R accepts the Foul. Ruling: After enforcement, the clock starts on the RFP.

Rule 3-4-2b3 (Action which caused the down to end did not also cause the clock to be stopped)

3.4.3F: K11 punts on 4th and 10. R1 catches the kick after giving a legal fair catch signal. Prior to the snap, K2 was illegally in motion. R accepts the foul for illegal motion. Ruling: After enforcement, clock starts on the snap

Rule 3-4-3c (Either team is awarded a new series following a legal kick).

Comment and question: In both situations R would have been awarded a new series but they were not because of a penalty. So because of this I'm thinking RFP in both. Additionally, in both situations the action did cause the clock to be stopped which makes me think snap in both. Can someone help me get my head out my butt and get this straight?
