I'll help you.

Indeed (tho I could tell you exactly when, but the abstraction provided
by syntax-* doesn't depend on that).
But right when you do the buffer modification, the text after the change
is immediately marked as "out-of-date".

No: as soon as you need to look at the `syntax-table' property, the
parts marked as "out of date" will have their outdated properties
removed+reapplied, so you'll be sure to get uptodate properties at that
time.
