If the horse is working 4 days a week without showing any signs of pain or discomfort, the saddle is probably fine. Its a decent quality saddle and while it sounds like it could use a reflocking, if it fits well otherwise and is more or less broken in to the shape of the horse's back, it's probably okay.
Personally, I'd leave your friend alone on the topic. It doesn't sound like he's interested in your opinion on his tack and being nagged by someone probably isn't increasing his desire to replace his saddle.
