CORE RULES p. 173 "REARWARD"Players choose their stance before a combat round sequence starts - they change stance simply by choosing a different one before the following combat sequence.
CORE RULES p. 174 "ENGAGEMENT"A character is allowed to assume this stance only if at least two other characters protect him by fighting in a close combat stance, AND if the total number of enemies facing the company isn't more than twice the number of characters in the company.
I would like an official ruling on this. If possibleA character is engaged when paired in close combat with at least one opponent. A combatant remains engaged until he defeats all opposition.

Ex. 3 companions are engaged with 3 Orcs, one companion is close to death and decides to remove himself from close combat, so at the beginning of the next round, he selects Rearward stance. Now his two friends will face the 3 orcs in close combat with the 3rd companion supporting from Rearward, out of harm way.
The rules say you can do it, and also that you cannot do it unless you have defeated your opposition.
Which is it?
I am really hoping for an official ruling
