I'll tell you what I think about this, and this is only my opinion.
Copying past giants is necessary. Most of the greats have copied someone themselves, often to a high degree of success. Take Ulf Wakenius for example. It's very obvious he has done a lot of Metheny transcription/copying. Lately he has found a little more individuality, but he sometimes sounded like a clone. By copying you learn things that aren't related with the notes and more with the music: rhythms, inflections...
There's an obvius danger to sound like someone you're copying by copying too much, and I think that's what happened in this case. It's allright to steal, but doing it from just one source is too obvious and a waste of resources. Plus, I wouln't record myself in that state, sounding like a clone of someone. It's allright to quote songs, or give a wink to someone with tone or phrases at a certain point, but come on, you can't base your career on someone's work if you respect yourself as a musician.
