He should be focusing on leadership qualities and things that make you a good leader (as opposed to a good worker) - things like leading teams & projects, good communication skills, people skills, etc. Depending on what your goals are, the focus of recs should probably be directed towards those goals. For example, one of my stated goals was working abroad around the world so my recommenders went into detail about how great I am with meeting new people & cultures and learning new languages.
In the end, it all has to tie in together - the last thing you want is for your recommender to write something incongruent with your goals and the rest of your application.
