It's just that his values are different when playing for the national team

‌Even just looking at free kicks,
he used to be the type to yield them to senior or junior national team players.
In fact, he has only been the dedicated free-kick taker for a few years.
It has mostly been since around 2020,
and even then, in situations involving a left-footed kicker, he would yield to seniors or juniors.
In most cases, he doesn't even attempt shots from long distances.
Because of his own nature, he likely has a mindset that since he acted this way, his juniors should too.
Even during his junior years, he never had any trouble with seniors.
At the very least, he is the type of player who isn't abrasive or attention-seeking.
While there might be cringeworthy episodes,
like kicking a water bottle or tossing the captain's armband aside,
his overall values as a player are well-rounded,
though not necessarily soft.
If you compare it to the military, it's like saying, "I might not be as strict as them, but my juniors still need to do what they are supposed to do"—that's basically his stance.
