I assume you used `C-x b' (switch-to-buffer) to switch back. If so,
this happens because dired-revert erases and then repopulates the buffer
it's called on, which relocates the markers used by switch-to-buffer to
find window-point when switch-to-buffer-preserve-window-point is t,
which is it by default since Emacs 26. If you set that variable to nil,
point will be where you expected after `C-x b'. Alternatively, if you
use `C-x d' (i.e. M-x dired) to return to the DIR-A buffer, point will
be where you expected (even if switch-to-buffer-preserve-window-point is
t). See bug#27243,
