Penalty assessments on dead ball fouls

[wisref2]

Can someone give the rule citation that gives A a first down on this one. I don't have my books handy. With dead ball fouls, doesn't the rule say that ALL penalties must be enforced prior to determining first down. The personal foul isn't an automatic first down, and after enforcing all penalties, A is still short of the line-to-gain.

10.2.4 SITUATION A: With third and 8 on B's 40, A1 advances to B's 35 where he is downed. B1 piles on and, almost immediately thereafter, A2 spears B1. RULING: Both dead-ball fouls will be penalized in the order of their occurrence. This is not a double foul. However, since the yardage penalties offset, the proper signals will be given and the line-to-gain equipment will be set first and 10 from B's 35 since the foul by B1 gave A a new series. However, if A2's foul had occurred first, it would not be a new series. If A2's spearing is judged to be flagrant, he shall be disqualified. (9-4-2i; 10-4-4b))

10-2-4 Penalties for dead-ball fouls are administered separately and in the order of their occurrence. A dead-ball foul is not coupled with a live-ball foul or another dead-ball foul to create a double or multiple foul.

5-1-2 A new series of downs is awarded:
a. After a first, second or third down, a new series of downs shall be awarded only after considering the effect of any act during the down and any dead-ball foul by B.
b. After a fourth down, a new series of downs shall be awarded only after considering the effect of any act during the down, except a non-player or unsportsmanlike foul.
