It seems that both are used for questions on looping animations, code
loop and shape/edge/face loops.
After discussing with Merlin, my suggestion is to make looping for looping animation and create a specific tag for edge-loop. Questions about code loops should have the loop dropped and retagged as python, scripting or something else relevant, this is not a programming SE so there should not be specific coding tags.
I volunteer to help retagging the questions if someone approves the edits (or someone with higher rep could just do it more easily).
