I'm not suggesting that the sitch in the OP was a legal slide.
I was asking in what scenario could you have MC on a runner while executing a legal slide.
The question is base on your earlier post:
"Who says you cannot have MC and a slide? The two things are not mutually exclusive."

If your comment did not assume "legal" slide then I understand.
