It is goalie interference. He clearly dragged the goalie away from the portion of the net where the goal was then scored, impeding his ability to make the save*. The goalie has minimal time to reset, not a few seconds as some posters are suggesting (try not watching it in slow motion).
*insert "juuuuuust barely" there
As a Jets fan, we've seen our goalies run over and lost the challenges and had goals taken away for similarly minor interference. So I have no idea how much you can interfere with the goalie anymore.
I don't think anyone, the NHL included, knows anymore.
