As I told you on http://emacs.stackexchange.com/q/19696/620,
(info "(emacs)Bidirectional Editing")
(https://www.gnu.org/software/emacs/manual/html_node/elisp/Bidirectional-Display.html)
suggests some methods to get bidirectional display right when you have
a paragraph with mixed scripts, but I can't make them work.

Anyway, this isn't limited to AUCTeX only, the mixed English-Hebrew
text is rendered wrongly also in fundamental-mode, so you may try to
ask for help on Emacs mailing list.

Bye,
Mosè
