Yes, in fact it does.
From Star Trek (2009):
KIRK: There won't be a next engagement. By the time we've gathered, it'll be too late. But you say he's from the future, knows what's going to happen, then the logical thing is to be unpredictable.
SPOCK: You are assuming that Nero knows how events are predicted to unfold. To the contrary, Nero's very presence has altered the flow of history, beginning with the attack on the USS Kelvin, culminating in the events of today, thereby creating an entire new chain of incidents that cannot be anticipated by either party.
UHURA: An alternate reality?
SPOCK: Precisely. Whatever our lives might have been, if the time continuum was disrupted, our destinies have changed.
Which would be just as true of a parallel universe.

It's an alternate reality/universe - not "altered," not "mirror," not "parallel."
The characters state this explicitly, in-universe.
In-universe, we know of only two such alternate universes.
This is not ambiguous. This is what is established as fact, in-universe and on screen.
