Yep, just the beam overall width is measured.
Some background, in case it amuses somebody. A long time ago the rule measured to the projected intersection of the deck and the hull surface, and it (brilliantly!) used a value that made any boat built to the plans illegal. The nature of the measurement also penalized radius deck edges, so if you wanted RM you used sharp edges and if you wanted comfort you used a radius. Or you added hiking ramps on top of the deck and hoped that the definition of "deck" meant the outer surface of the ramp. I (and most others) thought it was silly for the rule to make a person need to add ramps (not everybody likes the look...) to get the comfort
and RM, so the rule was changed to just a simple beam measure.
I think your image got cropped, and maybe this will work:
