When you say that a buffer is shown again in that window,
do you mean showing the buffer with C-x <left> and C-x <right>
or with C-x b?

When the tab-line will show the same order of prev/next buffers
after C-x <left> and C-x <right> or even after C-x b, does this
mean the order of prev/next buffers is not affected?
