The clarifications in P1787R6 did not address the core of this issue, so it is kept open. In order to avoid confusion, a wording change to clarify the treatment (regardless of direction) seems advisable. CWG felt that the first and second examples should be treated consistently, and expressed a mild preferences towards making those ill-formed. It was noted that the reference to id-expression in 12.3 [over.over] can be understood to refer to the id-expression of a class member access.
This issue is resolved by issue 2725.
