The question was to confirm my experience was correct, that the page doesn’t apply properly
to Quick Start and is therefore confusing. Thanks for pointing out the other page, but both pages
don’t reflect what happens with Quick Start. On the page you mentioned, I believe steps 4 and 5 don’t appear
from Quick Start which is the official way Apple recommends setting up new iPhones now. I think
the 2 pages list all the possible options for old and new phones and iOS, but maybe another page
is needed that’s specific to Quick Start, which automatically transfers your watch without erasing it.
