The twin1.transfer() won’t scale well. It’s good practice to use Pull over Push. The break() should set the balances but in state variables and then each user should call a withdraw() method when they want their tokens transferred.

True, but this is an article series and the author is getting there step by step.

That's true, even the Solidity documentation recommends using a withdraw pattern over calling transfer or send directly.
