I've seen that mentioned a few times, but I'm not sure why they would need to talk about welcoming him back if that were the case. That doesn't really serve much purpose for them does it?
They can just say he's in the program, we can't terminate his contract right now, and we'll see what happens later.
I'm not sure it's necessary for them to say things like the bolded below. They may think it's unlikely he adheres to the program, but I don't see the extra benefit in saying this, if they've totally closed the door on him returning.
CMac:
"We've got to look at all options to that. This time, priority one is for Val to get the help he needs, and you know, assuming he does, and after the six months, we'll have to read, and react on that, but it is very plausible that he will be back with the Avalanche."
Landy:
"Like Chris said, it's kinda up to Val now how he handles this. And obviously...once he comes back, and hoping everything goes well, and you know, he's ready to be a part of this team, we obviously will be ready to have him back, and be ready to battle out there on the ice, but yeah, we hope Val gets right, and we hope he gets what he needs, and he's able to come back and help us."
