So if the teacher had simply said, “yes,” but in her head, she wasn’t giving him permission, just stating that she believed he possessed the capability of entering, would he be able to enter or not?
Counterpoint: a welcome mat that says “welcome” or “come on in” can be used to circumvent such requirements.
I think it comes down to whether the limitation of entry comes from a restraint external or internal to the vampire. If there is some force that comes from people/houses that prevents the vampire from entering until consent is given, then I think you may be correct in that the permission goes as interpreted by the permission-giver. If it is a compulsion that comes from the vampire themself that they need to receive permission, then it comes down to the interpretation of permission as received by the vampire, and they would have more leeway to twist meanings to allow themselves entry.
Personally I lean toward the latter understanding as it is a simpler explanation of supernatural phenomena for such compulsions to come from the vampire’s psychology than explain some magical force acting on the vampire from the dwelling. It also makes vampires more sinister and therefore scary, which for a horror entity is good.
What about abandoned house, or dilapidated shack with someone in it? Does it need to be the rightful giving permission, or can it be a random person (i.e. can the vampire hire a squatter to let them in)?
Alternate ending: In life the vampire had been a logician, and thus intepreted the statement as an implied “yes”…
But he can’t unless he’s given permission. So until that happens, the answer is “no.”

That’s kind of in the same realm as all the vampires in the world suddenly developing an aversion to crossed sticks and blessed water in 33 AD.
And that’s exactly the sort of pedantry we’re discussing.
No, the permission needs to be granted verbally and explicitly. It cannot be implied in any way.

I then have a question of my own.

Better check the DM guide and roll a 12 sided dice.
