Weird, and a little bit of the trashcan. My two guesses are: they thought it looked sloppy, and don't have photoshop foo; or the designer was asked to hide something sensitive but didn't hide the right thing, and also doesn't have photoshop foo.
Hmmm, my best guess is they're violating terms of use for the strap. Maybe the strap is a component of a system related to a competitor's product, and part of the licensing of that system stipulates no use for development of competing products.
