M1 help--beginning knitter

Help please.

My hat pattern–Knit Santa Hat by redheart.com says to “make 1 increase: With tip of right needle, lift strand between last stitch knit and next stitch on left-hand needle; place strand onto left-hand needle and knit into back of it.”

Which leg is supposed to be in front on that picked up strand? ANd is that a knit into back or front?

I would still be on the double pointed needles at this stage of the hat since it is knit from tip to brim.

There’s 2 matching M1s to lean either way.

It’s the right leg in front.
