I think we all understand the purpose. The humor comes from the page not
being blank and the thought of a group of bureaucrats agonizing into the
wee hours over whether it should be "this page intentionally left blank"
or
"this page is supposed to be blank" or "this page is supposed to be mostly
blank" or "blank page" or . . .


Even important in classified documents, of course.

Why anyone who understood the essence would quibble over the wording is the
real question.
