I guess I don't understand what this is protecting against. Before this check was added, what was it doing? Surely the test XML of a create inside a check would fail?

apparently that wouldn't fail! it's not catastrophic, but that was theoretically possible before and it'd make the metrics slightly incorrect e

OK but if it wasn't failing, then what was actually happening? What does a create inside of a check do?

It would perform the create, but our metrics would mark it as a check because the metrics use the outer command type instead of any possible inner commands that might exist
