I feel like Lucas doesn't really care anymore so I could easily see him casually saying "yeah Disney's going to put out the old version that were shown in theaters."
As much as we all hate Lucas for his betrayal of the OT, ultimately I think not releasing the OOT was just him indulging in a bit of megalomania. People say he resents or is embarrassed by the OT and he wants to repress it or something but I'm not sure that was ever actually his intent.
