Yes, he's one of them. It's the same thing they did last year with Santana. The market was a lot like this last year too, even if Martinez and Hosmer and Cain were older and not nearly as desired as this year's Big Two.
McCutchen just suited the Phillies in myriad ways - similar to Santana as a high-OBP guy, good locker room guy (forget the intangibles there, even just his apparent willingness to talk to the press), more durable than Brantley, no QO like Pollock. He's still better than most of the remaining options, doesn't replace/displace anyone younger who is that valuable (IMO - YMMV) and is in no way an alternative or consolation prize for Harper.
And the Santana contract turned out to be rather easily moved; I suspect McCutchen in Year 3 will also be no big deal, whether he's a part-time player or gets traded or, worst case, fades into dead $.
