Is `switch-window-then-delete` misbehaving?

[drcxd]

I expect the behavior of switch-window-then-delete should be deleting some other window instead of the current one. When there are more than 2 windows, it deletes the window specified by the user input. However, when there are only 2 windows, it deletes the current one and keep the other. In the source code I can see that there is an alias delete-other-window for this function, so I assume currently the implementation of this function does not match its intended behavior?

Current implementation:

(defun switch-window-then-delete ()
  "Display an overlay in each window showing a unique key.
In the mean time, user will be asked to choose the window deleted."
  (interactive)
  (switch-window--then
   "Delete window: "
   #'delete-window
   #'delete-window t))

Maybe it should be something like:

(defun switch-window-then-delete ()
  "Display an overlay in each window showing a unique key.
In the mean time, user will be asked to choose the window deleted."
  (interactive)
  (switch-window--then
   "Delete window: "
   #'delete-other-windows
   #'delete-window t))
