That doubling at each level wording is actually taken from Krusty's particular penchant for wording. You should see Divine Sorcerer and Divine Wizard. I'd personally word it differently for just the reason you mention, but I guess Krusty does it differently so I'm stuck with it till he mentions a particular change.
I definitely agree with you though, it does sound confusing.
I will change it for Numinous Knowledge and Numinous Power which encapsulate both Psionics and Magic.
Here you go...
Numinous Knowledge (Su)
Prerequisites: Psicraft 40 Ranks (manifesters) or Spellcraft 40 Ranks (spellcasters).
Benefit: Double your number of Powers Known (manifesters) or Spells Known (spellcasters).
Special: This ability can be taken twice. Each time you take it, it applies to either your manifesting classes (manifesters) or your spellcasting classes (spellcasters).
Numinous Power (Su)
Prerequisites: Psicraft 40 Ranks (manifesters) or Spellcraft 40 Ranks (spellcasters).
Benefit: Double your number of Power Points (manifesters), Unique Powers per Day (erudites), and Epic Power Slots (manifesters) or Spell Slots (spellcasters).
Special: This ability can be taken twice. Each time you take it, it applies to either your manifesting classes (manifesters) or your spellcasting classes (spellcasters).
The ultimate simplification.
