I understand most of it, but still confused as to why andrew chains all of these methods together in one line.

$password.focus(passwordEvent).keyup(passwordEvent).focus(confirmPasswordEvent).keyup(confirmPasswordEvent);

From my understanding, he's checking the confirm box while the user is inputting the password. Am I on the right track?

Method chaining is a convenience and also makes code more compact.

You could always perform each operation separately, but since chaining is supported, it's convenient to just select the element one time and then chain all the operations you want to perform on it.
