Ah-ha! No, I'm just using a marker in the stitch itself. So in that case, I can keep the marker on the stitch and ignore the "pass marker" instruction other than to make sure that I'm in the right place? So I would still knit the stitch with the marker on it, and leave the marker where it is?
ETA: It's strange since the pattern doesn't mention this pass marker thing earlier, even though I had two hip markers through the bum shaping.
