[NTG-context] MPcode inserts page

Hi, if I use \startMPcode to declare variables etc. that I need in several MP graphics, it always inserts an empty page. How can I avoid that? (Actually, I load an external mp file, and for random value reasons I must load it only once. But the MWE already shows the problem.)
