Yes.  X11 doesn't have a notion of "workspace", fundamentally, so
window-managers simulate it by mapping/unmapping (the X11 terms for
display/hide) the windows according to which windows are displayed in
the current workspace.

Now mapping/unmapping is the same mechanism used to iconify/deiconify
a window, so Emacs treats an unmapped window as "iconified".

Note that window-managers could use other techniques to
hide/show windows.  E.g. they could just move them "out of sight", in
which case Emacs would consider those windows as still "visible" but
with bogus left/right positions.
