I have a bit of an issue with the Cover and Concealment terminology with regard to Hiding.
It assumes that cover is opaque. It also assumes that concealment is always behind something that conceals.
So, there are some scenarios that do not appear to make sense with regard to hiding with cover or concealment:
1) Wall of Force and Hiding. According to the rules, a creature could hide behind an invisible Wall of Force because the WoF blocks line of effect, hence, it provides total cover.
2) Certain creature position issues:
1 . . . 2
. . . . .
. . A . .
. . B . .
B has cover from 1. B has cover from 2. B can hide behind A simultaneously from both 1 and 2, even though he is 5 foot away from A and at least one of his opponents should always be able to see him.
3) A Blur spell.
It would seem that these cases are ones in which a creature should not be able to Hide unless other concealment comes into play.
