Are the results of single stage subliminal programs permanent?

[LionKing]

I wonder how resistance fits in with the snowflake theory? Does it melt the flakes as they're falling or does it just mean that there is another negative pile that higher from past experiences that's keeping the positive pile from becoming dominant yet, e.g. "I am only safe if I'm quiet" still has more flakes than "I can do, say, be or achieve anything"? If its the latter, then what happens to the negative pile once the positive one gets enough reps to become dominant? Fades due to not being used I guess?

This relates to how important it'd be to run "cleanser subs" like EPRHA or OF before multi-stages in the hopes having less resistance vs. just running the multi-stage twice.
