Booking dot com availability.

[br d]

Just booked an hotel through Booking dot com, I usually book direct with the hotel so I rang them first but they said they didn't have any rooms available on my dates. Went back to Booking dot com and it had 2 rooms available, booked one and received confirmation. Anyone had this before? I'm presuming Booking dot com has dibs on a few rooms so the hotel can't release them themselves, or am I misunderstanding?

Don't feel entirely confident that the room will be available when I turn up.
