What does each point on the color bar exactly mean ?
Does the yellow  (H) mean that if the right point (#3)  will reach the yellow point (H), than auto RTH will start? Or on which position the auto RTH will start?

Please read user manual page 12 and 13

I did it couple of time (I everytime read manuals), but I did not get it

Yes, if battery level goes down H mark RTH is initiated.. Tested

I've experienced it while filming. I was putting attention on video while RTH suddenly started.. I was scared from the event and far away, 2 km from home point.. But I got my bird back with no issues...

I have not read the manual, but I think I understand:
when 2 (H) and 3 are neighbors, you should go home.
H calculated according to the distance and battery, the return point, if you fly away over H, you will not have enough battery to return home.
H very helpful :-)
