To elaborate on what Czech said, that scene in Wedding took place in the Doctor's Universe. The alternate timeline was already negated by then. She simply came from earlier in Amy's timeline.

As far as Angels, this was in the Doctor's Universe as well. You may have noticed that the exact same footage was used in The Eleventh Hour. In what seemed at the time to be a dream sequence, with the TARDIS noise only there because sleeping Amy heard it. Anyways, this was clearly the normal reality.
