I see what he's saying. His example (Mrs Robinson) is similar to my example about the blues in F
The song "Mrs Robinson" is in Bb, which contains nasty chords that he wants to avoid. So he puts a capo on the third fret and changes the chords to start on the G shape. It LOOKS like he is now playing in G because his fingers are holding a simple G chord. But the capo converts his G to Bb - so really he is still playing in Bb.
It LOOKS like G but it SOUNDS like Bb.
The true key is the one that it SOUNDS like, not the one it LOOKS like. Here's the confusing bit. When he says "I am now playing in the key of G" he means as far as the chord shapes go, it looks like he's playing in the key of G and he'll think of it as being in G - but really (sound wise) he's actually playing it in Bb. If he records the song and posts it - EVERYONE will hear that it's in the key of Bb. Nobody knows (or cares) that he's actually fingering a G shape with a capo at the third fret.
