Indeed. I do like the ominous advice that just says "don't download it", and no mention of "you've downloaded it? bad luck then"
It's tricky to strike the balance though. On my desktop I allow the autoupdates to apply themselves, primarily due to MS having a surprisingly good track record of these updates of late. 5 years ago, maybe not, but today I'm reasonably confident MS won't blow my machine out of the water, and in the world of zero-day exploits it's worth that risk.. Plus I can usually roll-back a patch if need be.
However on my good lady wife's iPhone, I believe it's set by default to notify you of any updates, and ask you whether to install or not. She clicked "ok". Fingers crossed there's no issue, as on that particular platform there's no rollback possible.
