I can recreate this every time.
Step 1: Push South-East mirror 1 tile right.
Step 2: Push that mirror 1 tile down.
Step 3: Before it can be completely be pushed, step beneath it and cause it to slide back up due to you being in the way.
Step 4: Stand on the rewinder tile. It will appear here.
After that it's a matter of just pushing it up and quickly, easily solving the mirror puzzle here. Speedrun strats, yo.
