I think it also comes down to precision is most cases. "Recirculation" can refer to the process we call vorlaufing, but also processes involving paperwork and pool water. Ditto "foam layer" and others.
But "vorlauf" has more meaning than just recirculation of wort. There's clarification/filtration involved and settling of the grain bed.
Same for "kraeusen," which is both the foam itself, the state of generating the foam (high kraeusen), and (more obscurely in verb form) the process of using wort to prime while bottling.
Ditto "lauter": there's denaturing of enzymes (in the absence of a mashout), washing of sugars from the grain, raising of pH.
Plus, in all cases, you know the speaker's talking about beer. Each of these terms comes with a context (beer-makin' talk) and has both connotations and denotations that substitute terms just don't.
Best just to use the proper terms.
