I've done my rear diff fluid early on my last few trucks. The ring and pinion gears establish their contact patch with each other over the first 500-1000 miles and you end up with quite a bit wear metal. After the initial drain and fill you won't see that kind of metal again unless you have a problem.
Also, I'm almost positive the rear diff cover has a line etched into it about 1/2 inch below the fill plug and that is the fill line. Filling until the fluid comes out the plug means you overfilled the diff. That could result in oil leaking at your axle seals on each side.
