The Arcane Hierophant Companion Familiar class feature says:
Companion Familiar: Upon becoming an arcane hierophant, you must dismiss your familiar, if you have one (You do not risk losing XP for doing so.) [...]
This is puzzling to me because it seems that you just dismiss your familiar but you do not lose your ability to summon a new familiar (after a year of waiting), also it looks like your companion familiar is considered your animal companion while your familiar "slot" (let's call it so) is free, considering that it's a companion familiar with some (but not all) of the familiar features.
On top of that, should i enter the PrC from an arcane spellcasting class that doesn't have a familiar (say, a bard) and then i get one Sorcerer level then i get a familiar. The same should be true if I get Obtain Familiar (without getting sorc/wiz levels).
Common sense would dictate that once you get your companion familiar you actually lose your ability to summon other familiars but according to the class feature description you just dismiss it which is puzzling to me.
So, my question is if my reasoning is correct and i can actually get a new familiar a year later i dismissed my old one
