BxA likely letter?

I received a letter a while ago from a professor from a BxA program who is in the admissions committee and we spoke about the program I’m interested in over skype and it all went pretty well.
I was wondering if anyone else who applied BxA got a letter like that? Like if maybe it is some sort of normal protocol or maybe only those at the top of the applicant pool get that? I read in another forum of a student who got a similar letter but I don’t really know what to make of it.
