Not at all.
He explicitly calls out Blindsight as being equivalent... which is the only one on that whole list of abilities that actually allows one to "see". None of the others beat concealment, for example. If you have Blindsight, an invisible creature does not have total concealment. If you have Scent, Tremorsense, Blindsense, Uncanny Dodge, etc, he still does, and you can't "see" him.
In context, I think that if your foe retains total concealment, then whatever you have isn't equivalent to "seeing" them.
