Agree, and if he does leave in 2 years, more than anyone would have expected. He wouldn't be daft enough to 'confirm' that now though, 2 yeara is such a long time and so much can change.
I've admittedly not seen it myself in context, but the quote extracts sound like something he is consistent with saying preciously when asked on logevity. He likes to take thinga in small chunks, asess along the way, is always open to leaving when he feels it isnt right, and staying longer if it is. Not worth paying the attention it will be given by the medis imo.
