While the wooden joints can't over lap, I would argue that, the example shown is 1 bumper and not 2, which is definitely more then 6 inches.
We have to include the definition of a BUMPER into the updates to get the full picture -- A BUMPER by definition technically has a plywood backing, therefore it is also considered a 'hard' bumper by other clauses of the rule, which may not overlap in the corners. Hence, teams need 6" of a plywood-backed 'hard' BUMPER coming off of the corner of every side. Not only that, rule <R08-M> states that all BUMPERs must be supported by the robot, without gaps. This means you must have a piece of your robot backing the bumpers in every corner.

Hence, when you put all clauses of <R08> together, their drawing is correct and makes sense. We've had to rearrange the frame in some way or another over 8 or so drive train iterations to get it right to comply with the bumper rules . Next year the bumpers need their own section, lol.

<edit> Of course, as I write this I notice clause <E> that states BUMPERS must not weigh more than 18 lbs, so by what I just said the vertical pool noodles shouldn't count towards the weight of the bumpers. But common sense tells us that the vertical noodles are apart of the bumpers... So eh, perhaps they could re-word it to state that the minimum length of 'hard' bumpers must be 6".
