He has it mounted properly (according to Westins directions) The other bar you showed isn't Westin. You can tell because their logo isn't laser cut into the skid.

The brackets can be modified for a better fit though. They're two peices on each side. The lower piece gets turned around to bring the bar closer to the bumper, then the top part of the brackets gets about 1.5 - 2" cut off it to raise the bar up. Re-drill the holes to attach the to peices together and you're golden.
