"Go out, stay out" is taught in Little League, which is OK for a small field. Also, LL teaches umpiring to keep it simple, they aren't big on any sort of advanced mechanic, except a 1-3 rotation (which isn't really advanced).
Adding to this conversation, as the plate ump, when my partner goes out from "A," I'm reading he ball and the runner. If they're going to stretch it out into a double, triple, I'm not going out towards 1B, I'm heading closer to second.
