I think that the DELETE synopsis should look like
[ USING <replaceable class="parameter">from_item</replaceable> [, ...] ]
so that there's not any question which part of the SELECT syntax we're
talking about. I also think that the running text in both cases should
say in exactly these words "from_item means the same thing as it does
in SELECT"; the wording you propose still seems to be dancing around
the point, leaving readers perhaps not quite sure about what is meant.
In the DELETE case you could alternatively say "using_item means the same
thing as from_item does in SELECT", but that doesn't really seem like an
improvement to me.
