Default Brake Fluid Resevoir Diaphragm and level check

Sorry to start a new thread... i did some searching and found bits and bobs, but i just want to get some definate answers/opinions.

When filling brake fluid into the handlebar resevoir, how do the fill level lines work? I gather the markings on one side are for when the bike is on the stand and the other is for bike level? Which is which, and is this with the bars turned/locked?

The reason i have a problem here seems to be the diaphragm under the lid, mine is totally expanded... i assumed this was to dampen the fluid and make sure fluid was always available at the supply line. However, i now beleive this diaphragm should be collapsed upon refill? So it can then expand?

I will be totally re-doing my front calipers on saturday, so i could do with knowing the answer to those 2 things in time for that.
