Yes, from the excellent dissection work, it's clear why the vac retard port (A) did not leak but the boost retard port (B) did. The housing's vacuum section did not leak. The diaphragm sealed it from the housing's boost section which was open to atmosphere and thus leaked.
For the assembly to have ever worked properly, the B or boost press port had to be sealed where it entered the housing.
