most of the episode was unclear to sam in terms of whether she was hallucinating, and she was very unsure of what was reality and what wasn't, and i think that that moment was there to show us that a) she was back home and in reality again and b) she knew she was back and in reality again.
i also think it was there as a catalist for character (and story arc) development (for discussion in a different thread).
