Can you give us the name of the pattern or a link to it?
It looks like you drop the next stitch and let it ladder down.
Take the tip of the right needle ans insert it under the ladder from front to back.
Let the tip protrude through the space between the top rung and the lower 5 or so rungs from back to front.
Grab that top rung or strand and bring it through to the front under all the other strands and place it on the left needle.
Knit that new stitch and proceed.
I’m not sure this description helps but maybe added to the photos you can make it work. I’d try it out on a small swatch first. If i can find a video, i’ll post it here.
