That is correct, but the GP said:

Which is 100% not true, it's not like a personal check. You are only at risk if:
* your counterparty decides to try and cheat you (despite knowing they will lose even more money if they attempt to screw you and you notice, so some game theory is involved)
* you are not watching onchain for a period longer than the monitor period (typically several days)
* you have not elected to have someone else monitor on your behalf (in exchange for a small cut of the "profits" if your counterparty tries to cheat you)
My point being - it's nowhere near the same as a personal check.
