Many banks in Saudi Arabia have changed their standard for PIN length from 6 digits to 4 digits. I cannot comprehend why would anyone make such decision.

Many international withdrawals only do 4 digits which means 6 digits in your home country becomes meaningless...

they should fix the underlying problem but in the meantime, they probably could just automatically truncate to 4 chars when 6 can't be used?

No, because certain combinations, e.g. 1111 are prohibited in four digit codes but wouldn't be at the start of six digit codes.
