It's partly for the same reasoning as before - Sherlock has met Connolly - but also because, yeah, Peter can't spare any of the men he's got on duty.

"He'll have a first aid kit on him," Peter says. "He's trained on how to use it. All my men are."

And if it's necessary to take Sherlock to the hospital, Connolly will do that, too. Peter thinks not mentioning that would be the wisest course, though.
