Max Power Points?


I found yet another description / text contradiction I'd appreciate if someone could clear up.

According to what I've read, MPP is BPPx2. However, in the description on page 192 (the one about Ankh-af-na-Khonsu), his BPP are multiplied by x3 in the start of the description, and then by x4 by the end of the description.

What am I not getting here?
scholar class ability level 6:
Increased Maximum Power Points (triple)

Level 13:

Level 20:
