It happened regularly throughout the series too. I'd guess whoever made the meme hasn't watched the show or hasn't watched it in 30 years and were hazy on the details.
Also, apparently there's an episode where Spacely and Cogswell are arguing about real estate and they discuss a rule of Orbit City which requires all buildings to be at least 2200 feet off the ground (I assume from their "bottom"), which would make their homes roughly the top floors of the Burj Khalifa
