We deduce bool& in the first decltype: finish_decltype_type gets a VAR_DECL 'b' (that's wrong I think), id_expression_or_member_access_p is false (that is correct). lvalue_kind then of course reports that the VAR_DECL is an ordinary lvalue, and we deduce to bool&, just like it were decltype((b)). So the problem must be that we strip both NEGATE_EXPRs.
