Humans are not perfect, some of us get angry at the perception of being superceded by those less experienced. Some will dig in their heels and not fix the issue if it means admitting they were unable to see the problem and suggest a solution.
So that's the beauty of how it was communicated. No blame was placed on anyone, plausible deniability was given out to everyone, and he pre-empted being derided as a layman who doesn't know shit by pretending to accidentally discover the issue. In one fell swoop so many egos were placated and a plan was laid out on top of all that. No back and forth, just all boxes checked and all given license to proceed forward with enthusiasm and intent.
