Is the vent port to be opened before the vent valve, as suggested in this video in 1:25 - or the other way around? First the line should be vented out through the vent valve before opening the vent port to prevent spraying right? Again this contradicts what is said in the earlier part of this video (1:03) itself.

Interesting and good animation

👍
