When input configs with disabled state validation button, the button state will blink.

This code works fine, but I don't know what exactly it solves, or what was wrong with the previous code?

Sorry to make you confuse. It's just a minor issue, the validation button will blink when you input. You can check the validate button behavior in the below video:
