If he has short-term memory loss it’s of course also possible that such a move is intuitive.
When I say here liberties than I mean the amount of moves that it requires to capture a group.
In a fight it’s useful to have that number in mind.
If you have a fight between two groups than the situation isn’t really wide open like a Joseki.
Reading 10 moves ahead doesn’t mean that you see every possible variation but one variation that includes reasonable moves from both players.
You don’t want to spent time reading out the variance tree of a Joseki every time you play it from scratch. It’s also not always straight forward to know what result is better.
If it possible to start an invasion in the corner? To judge whether it’s possible to invade a corner you might well have to read 20 moves deep.
How much points is the influence really worth?
Bad Joseki moves often only make you lose a single point.
Lastly learning Josekis is a way to learn how stones flow in the beginning of the game. You need a bit of a feeling of how a game flows to be able to read far ahead.
