Foul by B

NFHS rule 10-4-7 has me thinking. It says:

a) 1st and 10 from the A10. A8 drops back to pass and scrambles into the EZ where B51 grasps, but does not pull, A8's facemask. A8 is tackled in the EZ.

b) 1st and 10 from the A10. A8 drops back to pass and scrambles into the EZ where B51 grasps, but does not pull, A8's facemask. A8 fumbles and the ball rolls out of bounds at the A3.

c) 1st and 10 from the A10. A8 drops back to pass and scrambles into the EZ where B51 grasps, but does not pull, A8's facemask. A8 fumbles and the ball rolls out the back of the EZ.

All these plays have A responsible for the ball crossing the EZ, and have loose balls. In a) and c), it is 1st and 15 from the A5, no? But b) confuses me a little. The rules says the basic spot is the goal line, "regardless of where the loose ball becomes dead." Does this mean 1st and 15 from the A5, even though the ball became dead at the 3 (rather than 1st and 12 from the A8)?
