I think he's Te base. His sense of humour is almost identical to mine. LSE > LIE.

You might be confusing Fi suggestive for Fi PoLR. An important thing to point out is that his criticisms of people are often things he catches himself doing, like using his phone too much and complaining about the lack of WiFi on aeroplanes, which he then turns into a rant that seems to be directed towards others and not himself. In this sense, he's critiquing his own behaviour.
