Every iteration of #Phil both exits and loops #Punxsutawney (February 2nd).
He is copied back to the previous point with no consequences, but also the new iteration moves forward on that timeline with all the baggage of consequences of his actions.
The end of the movie is not "Phil escaping" but rather us (the audience) following one of the "off-ramp" copies instead of following the loop.
He is still there, #looping and splitting across time.
