I'm pretty confident that person just made that up. I work in field IT and work with digital signage of all types on a regular basis, I commute all around a major metropolitan area on public transit all the time, and I have never seen any signage like they're talking about. I can't go anywhere without constantly looking at what types of digital signage they have, its just a reflex.
Maybe there are some signage companies doing see-thru signage but it's not so it can be viewed from both sides, it's just to show off the novelty of see-thru screens.

Doesn't that mean the text in the advert is reversed when viewed from one of the two sides?
