I find it difficult to see the difference -- and therefore when to

Is there someone who will enlighten me? Because I hate not knowing
what I am doing.
say that you have a background behind framed:
compare:
\startuseMPgraphic{test}
draw OverlayBox withcolor red ;
\stopuseMPgraphic{test}
\setupcolor[state=start]
\defineoverlay[test][\useMPgraphic{test}]
\starttext
\framed[background=test]{Hans}
\framed[background=test]{Hans van}
\framed[background=test]{Hans van der}
\framed[background=test]{Hans van der Meer}
\framed[background=test]{Hans}
\stoptext
compare: use, reuse and unique and you'll notice the differnece:
use: every time (i.e. 5 mp runs)
reuse: once, each framed gets the same background (some have wrong
dimensions)
unique: 4 runs, the last one has the same dimensions and is shared
so ... unique is able to determine if it can reuse (based on
configurable characteristics)
