CMS Split Screen Opposite Scroll

I’m trying to recreate the example on this page where the content scroll through opposite directions. I’ve found a few cloneables for how to do it for static content but I just can’t get it to work for a CMS collection. Anyone have any ideas?

EXAMPLE: example I’m referring to is the services section- " some of the things we do"
READ ONLY LINK This is how we want the cms set up then the image and the content should scroll to the next portfolio piece in opposite directions.
