Stair-Step Bumper Design - Legality of Tetris-style bumpers

[AccurateFilms]

The soft parts are definitely the only ones past the corner, but we have determined that this way the impact is distributed along both axes instead of just one. Since the bumper is specified as two pool noodles, with only soft parts past the corner, is this not qualified to be part of the bumper? The backing must be 5", however the soft parts are two 2.5" pool noodles. In our design, both pool noodles are 2.5" and backed by 5x3/4" plywood. However, the corners even allow for a single vertical pool noodle, so why would two 2.5" noodles not be qualified? Could you specify which rule disqualifies this bumper setup?
Also, if we were to have an overlap design (say, the side panels are longer than the ends by 2.5" in each direction), wouldn't it suffer more from bending outward from the bumper zone? In our design, an impact that would normally be exerted on a side panel is partially distributed to the front panel. Here is an illustration.
