Scrolling Behavior – Mobile vs Desktop

We have some internal research that shows our users scroll much further down the page on mobile vs desktop. The page lengths are exactly the same in terms of the amount of products displayed - 3 across and 12 down.

When describing this behavioral difference I call it the 'Facebook Phenomenon' as in users just scroll endlessly without fully absorbing the information presented to them.

My question is, is there a UX/analytical term for this behavior? I made up the phrase 'Facebook Phenomenon' where I work but wondered if I'd subconsciously copied something I'd read.
