It's mean because it's along the lines of the oh-so-annoying "it was just a dream" device. At least it only affects the last two strips, if Rich had this going for five or more (especially with the strip's usual delays) it would have been truely irksome.
But Girard was an epic illusionist! It had to be done! And assuming that that little sequence will have no consequences in the story is premature. Dare I say that that would be the real illusion (despite the oximoron)?
