Certificate check result is false, even though SASL EXTERNAL is successful:

While certificate is correct, it doesn't match domain hence it's marked as invalid. We shouldn't even start trying to establish SASL-EXTERNAL in this case as the return connection will surely fail.

I was pondering it a little bit more and I think that with #issue #1112 and #issue #1132 we could actually stick with && with the assumption that it would still be possible to establish and authenticate connection in one way using SASL-EXTERNAL and other way around using dialback.

Without those two tickets sasl-external should not be advertised.
