>I don’t get it. There are two (harsh! Direct!) statements, followed by a relatively low-emotional-intensity question. So the “these should be statements” angle doesn’t make any sense to me, they’re already statements. Are you expecting people to just say “cut it out”, with no conversational room for a discussion?

Depends on the situation. A reliable employee that suddenly starts showing up late would get the "Is everything ok?" talk. A perpetually late employee on there last strike would get the "cut it out" talk without a lot of need for discussion. The point is that you need to pick one. A "cut the crap but is everything ok?" message doesn't work.
