The wording of the rule can be confusing. The FRAME PERIMETER and therefore the BUMPER PERIMETER is defined by the
outermost set of vertices. In the example you provided, those would be the four outer corners of the robot. The FRAME PERIMETER does NOT include the two corners set back in the frame cutout, because those are not the outermost vertices.
Therefore, when you perform the string test, you get a rectangular loop of string which wraps around the four corners of the robot, and does not protrude into the cutout. It's a very long-winded way of saying you can't have part of your bumper perimeter which is concave.
With the string test above, you can see that the string goes across the gap, and therefore represents part of your BUMPER PERIMETER which does not have support for bumpers, and is illegal per rule <R07> K.
The rule is functionally identical to last year's bumper rules.
