Does step 7 of Cleanup allow Surprise Defense to stage combat?

Ruling: Step 7 of Cleanup does not properly allow Surprise Defense to stage combat as written, but rule 434 offers another moment outside of step 7 when combat could occur as a result of cleanup. The wording of step 7 appears to be incorrect.

Nuances:

• If player A applies contested status and the battlefield is controlled by no one, then no one is "different from player A" so step 7 should apply
