That is expected.

I guess the Admin Guide has a bug then. What exact section are you referring to?

That's also expected, since hasSubordinates is a dynamically generated
operational attribute (and also read-only, as I recall). You need to exclude
any dynamically generated operational attributes from the syncrepl search.
E.g. 2.4's test045 specifically tests this scenario, and the syncrepl spec uses:
retry="5 5 300 5"
In general, while this is known to work in 2.3, you're better off using 2.4.
(We intentionally did not include test045 in 2.3...)
