What it was meant to represent is back up what you say you are going to do.
Additionally (and the main point of the equation) is don't over talk a route or give any more discussion to something you climbed then the climb merits.
I believe Blitz's comments were aimed at particular FAs that were sprayed about way more than the route actually deserved in mags, etc as the climbers were trying to appease sponsors among other things.
Yeah mathematically if fails but its more meant as a simple one liner response that has semi morphed into the tag line for the brotherhood.
Blitz makes a great point IMO.
