Hmm.  The code is perfectly clear about it, see DetermineTimeZoneOffset:

    /*
     * It's an invalid or ambiguous time due to timezone transition. Prefer
     * the standard-time interpretation.
     */

but right offhand I don't see any mention of ambiguous times in the
likely parts of the documentation.
