Unless I misunderstand you, no, this cannot happen. and always move in opposite directions in the buffer at the same buffer position, because they invoke opposite buffer movement commands (forward-char or backward-char) on identical conditions. If invokes forward-char, then will always invoke backward-char at the same buffer position, or vice versa. If I'm mistaken, please show me an example where what you say can happen does happen.
