Conceptually both, ‘pop-to-buffer-same-window’ and ‘switch-to-buffer’,
behave alike in this regard: They avoid the minibuffer and windows
strongly dedicated to their buffers.  Interactively, ‘switch-to-buffer’
may show another buffer in a strongly dedicated window when the option
‘switch-to-buffer-in-dedicated-window’ is non-nil, but I suppose the
issues mentioned in this thread are not about the interactive use of
‘switch-to-buffer’.

If the dired buffer was earlier shown by ‘switch-to-buffer’ and is now
shown by ‘pop-to-buffer-same-window’, the behaviors should be the same.
Quitting the dired window, however, may behave differently.
