Yes, you are reading correctly. Another copy & paste mask tutorial. A member of my nursing staff could have possibly avoided a warning if he had looked at the mask before trying to put it on the wrong way round again and again and again. What is logical for ordinary mortals is apparently quite extraordinary for a trained intensive care nurse with expert training in home ventilation. The mask actually has a top and a bottom. So when you assemble it, it makes sense not to ignore the up/down labelling on the mask.
So let's go, let's go.
Press the mask cushion onto the frame.
Hint: Make sure that the size indicator of the mask cushion is facing downwards.
Attach the upper headgear to the mask frame by looping it around the two upper headgear hooks.
Note from myself: The upper Velcro fasteners are never opened. I am serious about this.
Attach the elbow by pressing on the two tabs on the side and slide the elbow into the mask.
