As I said, in my games the Combat between groups of opponents is fluid. There are six Orcs and two Barding swordsmen in the second round of the example. Following the very basic rule, the third Barding can use his bow. It's really just as simple as the LM and the Player adjusting the narrative to suit the situation's needs and Escape Combat doesn't ever need to come into it, unless the character is attempting to hightail it.
I have no difficulty at all with envisaging a situation where the Barding swordsmen, despite facing other foes, have manoeuvred themselves into a position where they can obstruct their full quota of opponents, allowing their third companion to retrieve his bow and enter Rearward Stance.
I just think that it makes for a better game. Purely my opinion, of course.
