It appears that at this point the pattern would change, since you'd been doing yo's up to this point. Now you're working without the yo's--just knitting and decreasing. You no longer need the second marker from each set since you don't need them as a point of reference anymore.
From this point, only follow the instructions to the markers that are still on the needle, not to where anything was previously.

Hop aboard while we follow the cloud-covered van of knitting harmony, man!! Woooo!! --Hedgehog
