Yes it is slightly over the top, but I'm guessing he's serious about his photography. If you find that guy's mounting position suitable why don't you follow suit but use bungee cords instead?

*edit* What camera set up did you get btw? I've just upgraded my Nikon F801 for a D90, will hopefully get it by the weekend. It's my first DSLR after using some of the older SLR's, like the Nikon, an Olympos OM2 + the Mrs' Canon A1.
