Perspective does not require 3d.

You can have perspective in flatland.

You're right, this is definitely not really 3d. It's more of a trick to give the illusion of perspective to a 2d scene.

Made for some nice games in the early 90s, though!

I think you're right, its a sort of pseudo3d. Its a 3D presentation of a 1D (2D environment) perspective. Cut a horizontal row of pixels from the center of the screen and you have its flatland point of view.
