Hmm.  On second thought, maybe you meant to continue pressing
<right-arrow> _after_ reaching BET.

In that case, what you see is a side-effect of a feature: the effect
of <right-arrow> is different depending on whether point is in a
left-to-right paragraph or in a right-to-left paragraph.  In the
former case, <right-arrow> advances _forward_ in the buffer, but in
the latter case, it moves _back_.  (This is so pressing <right-arrow>
would move to the right no matter what is the directionality of the
paragraph.)  When you move from a left-to-right paragraph to a
right-to-left one, the meaning of <right-arrow> changes, so you need
to press <left-arrow> to continue moving forward beyond BET.
