Done! But same result :-(

at the end of mp-mlib.mp add
def resettextexts =
_tt_n_ := 0 ;
enddef ;
extra_endfig := extra_endfig & "resettextexts ; " ;
then run
ctxtools --touch
context --make (or texexec --make --luatex)

A much smaller luatex test is possible:
\startuseMPgraphic{a}
label.bot(textext("a"), origin);
\stopuseMPgraphic
\useMPgraphic{a}
\startuseMPgraphic{b}
label.bot(textext("b"), origin);
\stopuseMPgraphic
\useMPgraphic{b}
There is some problem with the textext array indices, it seems:

Re: [NTG-context] Strange problem with metapost graphics
Hi. XeTeX result always have some offset compared to the pdftex result. I don't know why. Moreover, it is impossible to use opentype (at least I never use it successfully.).
