Help with sock pattern

Hi, I have a pattern from sock innovation, pattern name Kai-mei. It says “pick up 4 strands of dropped yarnovers, purl 4 strands together with next stitch”. I don’t understand this part. Could you please help. Thanks


Bring the right needle down the 4 strands and lift them up to the left needle. Purl them together with the next stitch.
It’s somewhat like the butterfly stitch. See about 4 mins on this video. Admittedly this is done with slipped sts and on the knit side but the idea of working the sts together is there.

Have you found an edited version of this pattern? There’s seems to be a long list of errata although I can’t get to it.
