Yes. I don’t see Dumbledore in canon being so stupid as to fail to either ward his room against time-travel or recognise that that was how Harry got in.
Come to think of it I can’t see MoR!Dumbledore being so stupid as to not recognise it. Not only does MoRdore use timeturners heavily himself and strategically analyze time loops with Snape he has also seen (some of) what MoR!Harry has managed with them previously.

One does not simply timetravel into MoRdore’s office.
I think he’ll probably work it out exactly three hours later, when Professor McGonagall shows up outside his door.
