That's totally the essence of Peter, and you may be assured that it's genuine, and from him personally -- that's him all over.
I once, sort of similarly, got a letter from Peter that began with an apology for his managing to misplace my correspondence. He wrote something like, "What happened was ....well, never mind, I really can't tell you, it's just way too embarrassing."
After which, he went on to say many gracious and also very funny things.
He is one "star", who also happens to be a great actor and a unique talent, and who never, ever forgets that for all of his abilities and genius, ultimately it's the fans who make his success possible.
Some actors regard fan adulation as a burden or a nuisance -- but Peter understands that it is a great gift, for which he is always grateful.
