Hi Tim.

Does he just mean playing chords in different positions on the fret ?

Yes, I think so. That is the way I interpreted it.

If chord progressions are achieved by using barre chords up and down the fret board, with only a limited number of chord shapes, then the result may technically meet the requirements of the tune but could sound a bit boring. It could also tend to limit the chords used to the more obvious major, minor and 7th rather than more subtle augmented, diminished, minor 6th, etc. I think that this is what is meant by "boxy".

I don't think it has anything to do with parallel harmony. Correct me if I am wrong, Josepp.
