He's on record as saying that Inaba is Josh speaking as Josh (unfiltered), and BFL_Josh is Josh speaking as the BFL rep.
No, Josh always uses his Inaba account - even when talking about BFL in his role as company representative.
Go check his stats:

I thought BFL stopped using bitcointalk for official statements anyway, the info you just posted kind of supports that as well doesn't it. So anything Josh posts here these days is HIS PERSONAL views/estimates, as was already said.
