There are lots of ways the rocks could have been set in motion, the relative size of the rocks have little to do with anything, (see later).
Ejecta from larger impacts, what you may be seeing is the last leg of the landings, where a trail of the first landing after impact could be miles
ways, in a different LRO swath. Same for smaller low angle impacts, a trail could be 50 miles or more and we are viewing the last leg.
Its apparent these rocks are on an impact slope, in a crater. Has anyone been to the Arizona impact crater? You get near the rim its a vertical drop,
you feel you almost can fall in, (I get vertigo until acclimated with drops), then it slopes to the base. A lot of larger lunar impact show a lot of
fill-in, where the base is higher than the Arizona crater, meaning the slopes could be steep all the way down to the base.
Size is deceptive viewing the moon from space, those holes can be deeper than the Grand Canyon, sometimes 3,000 feet deep.
With little erosion on the moon some of those trails can be hundreds of millions of years old.
Lastly, the size of the rocks in lunar gravity reinforces the inertial momentum needed for long trails. Again these rocks on this thread didn't stop
at the base of the crater they are in, I suspect the slopes are quite steep.
