I understand your point, but...
1. You're seeing just a clip of the end of the song and not the word sung in context, which is...
2. An accented syllable at the end of a lyrical line which rhymes with the previous line...
3. And is a big rallentando and ritardando (slowing the tempo and doing it more and more so) in preparation for...
4. The punchline of the song ("part of that world").
All those points support an extended stay on that syllable.
It would tho, indeed be incredible awkward, if done for each time that refrain comes around.
