how not to help someone

Fin 'helped' me to edit two reports today by sending me back changed copy. When I suggested that comments like, 'this paragraph needs to be more concise' would have been more helpful, he said (verbally patting me on the head) that he knew I was smart enough to read the new version and work out for myself what changes had been needed. Uh, yeah. Can we say, 'missing the point'? It also presumes that his version was better, which I find irksome.
