Correct...the concept is that each time you push the pedal down, that much fluid will get pushed down the air filled line. So , if you close the bleeder each time , the master will not suck what you pushed down the line back into the master..eventually, you will have enough strokes to have the fluid push all the air out the other end .. the fluid chases out/replaces the air...that's all.

Just never let the pedal UP w/bleeder open or the fluid is just going back/forth..you want it going out the master, not returning..it is the closing of the bleeder each time that accomplished that. And watch the fluid level all the time b/c if that compartment get low , you are pushing air into the lines again..like you probably did the first time.
