Thor was seen by his mother on Asgard when he went back in time, yes. But no event was changed. His mother still died and the hammer that he took was placed back in the same time it was taken from after it was done being used in the new time during the final battle. The past Thor still goes through everything that originally happened because the same events still play through for him.
