I think the rules committee made a creative interpretation to allow a frame side to be less than 8". The rules committee does not have to make sense. To quote Lily Tomlin "They are omnipotent"

Now tell me where that quote came from.
In terms is the pic legal? Only your inspector will know for sure. But you bumper will have to comply with R29 & wrap around the 1" fillet so that is is fully supported.
R29
BUMPERS must be supported by the structure/frame of the ROBOT (see Figure 4-6). To be considered supported:
A. a minimum of 1 in. at each end of the BUMPER must be backed by the FRAME PERIMETER,
B. the gap between the backing material and the frame must not be greater than ¼ in., and
B. no section of BUMPER greater than 8 in. may be unsupported.
