As others have mentioned, the strip makes it incredibly clear that they escaped from the illusion. The purple tint for its entire duration, the fancy graphics and the way it advances Elan's plot development are all very obvious.

It's not going to come up as a serious misunderstanding - any further threads would probably be comedic and not need or want 'clarifying', and the people using it as some way to retcon stuff they don't like about Tarquin will just find some other way to retcon or reinterpret the things they dislike.
Either way I can't see where the quote would be useful after the current pro-Tarquin discussion has died down, so I'm voting no.
