You need to call the setglobalmacro(...) macro. The code inside
\startMPinitializations is only executed when you call any MP environment. But
you are using \udCount before \useMPgraphic. A simple solution is to run dummy
MP code so that MP initializations are run:
\starttext
\setbox\scratchbox\hbox{\startMPcode draw unitcircle; \stopMPcode}
\dorecurse{\udCount}
{\useMPgraphic{foldUD}{num=\recurselevel}}
{\useMPgraphic{dotLines}{num=\recurselevel}}
\stoptext
A run with no sideeffects in the content stream is:
\startMPcalculation
....
\stopMPcalculation
