Confused about thumb gusset instructions for gloves pattern

I’m a beginner-ish knitter working for the first time in the round on dpns making some fingerless gloves for my brother - http://www.knitlist.com/00gift/mens-fingerless-gloves.htm

I’ve managed fine with the ribbed cuff but the thumb gusset instructions have me a little confused, especially where it says ‘k2 rounds even, keeping the p1 sts uniform’ - what does that mean? Do the p1 sts stay in the same place in those 3 rounds and then do I change the purl st positions? I’m finding it really hard to visualise at the moment.

I’d be grateful for any help you can throw my way!
Thanks

It seems to be a strange way of saying that while you knit two rounds even, you’re still supposed to purl the purl stitches. I think it’s so you don’t read “knit two rounds” and just knit all the stitches around.

Thanks for clearing that up :slight_smile:
I was worried that by the time I figured out how to knit these up for my brother it would be Spring (I’m a very slow knitter!)
