The masks require YOU to take an action, that is what you are instructed to do and need to know about.
The descent is handled entirely by the crew, you don't need to do anything while that is achieved.
The instructions are best remembered as an absolute minimum set. There will be a large number of other things happening around. For example, as the masks deploy people regularly comment about "all that dust" that happens. It is not dust, it is French Chalk that the masks have been packed in to minimise the chance of them snagging. You don't need to be instructed on that either, just the grabbing motion.
