So is there a way to circumvent these issues? Or an explanation for this behavior, so that I can try to find a solution by myself?
Thanks

Dear Aditya and Fabrice, thanks for your responses.
I included some of Fabrice's code into mine for testing purpose, and indeed the multipage works now. What is bizarre is that issues appear now that didn't appear before: Path A is drawn with color red on page 1, and in color black on all following pages, while it should stay red.
textext(<text>, <pair>) is overwriting <text> with "T="&decimal(currentime) which has been used previously in textext() before the for k=1 endfor loop. This overwriting happens only for the first textext() which occurs inside the for k=1 endfor loop. All other textext() inside the for k=1 endfor loop are not drawn at all. If the line « draw textext("T="&decimal(currentime)) scaled 2 shifted(0,2in) withcolor magenta ; » is commented out, the first textext() inside the for k=1 endfor loop is not drawn neither. It must be an issue with textext(), because when I replace textext() by lmt_outline[], the text is drawn.

Hi,
It is fun fact very easy to do. You just use \startMPpage (…) \stopMPpage multiple times. Here is an example which build an animation of a particle moving according to a Brownian motion.
A very similar option is to pass a variable to a metapost drawing. This is what I use: https://adityam.github.io/context-blog/post/metapost-animation/ It only works when viewed in acrobat, you can just comment out the animation part and wrap it in \startTEXpage .. \stopTEXpage to get multi-page animation.
