Motor flush on oil change requires cold engine?

Motor Medic Motor Flush - 1 qt (Not 911. 2007 Jeep 3.7L)

Add to full crankcase when engine is cold. Idle engine five minutes. Shut off and drain.

I read the directions after I have already warmed up the engine for ten minutes.

I look at the contents and it's #2 diesel fuel and kerosene plus distillates.

I'd rather do it with the oil hot. However, I have no idea why it's supposed to be done when cold.

Thoughts?
