I don't believe so. Really no reason they can't talk about them now but maybe Ash, and/or other coaches, prefer to wait until they're on campus. Who knows?
The whole PWO area is a bit tough to follow & sort out as far as 'rules' - but what I believe is the case is that the PWO needs to have made their way through some 'official' on campus orientation and/or made an initial fee payment of some sort signifying an 'official' intent to attend.... then the coaches can discuss them & can begin to interact with them in accordance with prevailing coach - athlete rules.
