Help me beat this confusing formation

[Kylos]

When you choose to pass down one flank - does left/right mean their left/right flank or yours? I've always assumed it meant yours, but I'm not sure, and it could make a difference in a few cases each season.

I presume its yours, as the orders being set up is yours.

[John Naish]
