That's within the range of patterns the ejected brass displays for any of my Lugers. I'd say it varies with the particular pistol. Although they were meant to generally fly up, small differences can result in different brass trajectory. I'd say as long as they're exiting the action and not winding up down your shirt, you're doing great.

If they all go up onto the roof, that sounds like a dandy way to prevent their getting mixed up with other brass! Save that brass, even if you don't reload, reloaders here will be glad to have it!
