Actually this is the simplest way to test:

(setq highlight-nonselected-windows t)

Create a buffer: test

write some text there and select a part of that text (so you see the region)

Then from scratch try commands like (just an example):

(with-current-buffer "test"
  (right-char)
  (insert "X"))

Or similes several times...

You will see that the region is not updated.
