The other part is that coaches teach players to slide to avoid tags & collisions; so then players think they must slide and that translates into a rule in their minds.
It's like the turn after overrunning 1st base. Players are taught to turn right to "avoid being out", that becomes a rule in their minds.
And others, usually actually believed as rules by the coaches who have never been umpires.

I've seen lots of tournaments and in-house leagues that have a must slide rule. I don't think it's hard to see where the idea comes from at all.
