Whats the technical reason for this ? The markings are hand made, and appear to indicate the points where the clutch kit and flywheel are balanced from the company.

However, if we are re-using the flywheel, it doesn't make any sense to try to align them with 180 offset.

As you suggest it's for balancing. This sheet of instructions comes with the clutch, let's see if it works:

Edit: Looks like it doesn't... you can get it by going to the zf webcat site https://webcat.zf.com/?SPR=4 then search for the clutch kit for the e60 m5, open the clutch kit PN then look under assembly information.

Now you reallly have to beat on it to get it to fit wrong, and if you do you might crush the dowel. IT's replaceable if you have to.

What aftermarket flywheel did you get?
the flywheel has clear markings on it ^-^, Roger That.
I think the mechanic just placed the flywheel on the crank, aligned the bolts, and went to town with the impact wrench, that's how they do it lol. There were shiny scrape marks on the dowel when he took the flywheel off. He doesn't clearly remember how it was aligned. I asked him to work on it slowly, hand torque it, and work on it in his free time , no need to rush with power tools on the flywheel and clutch.
