That's how I use them and it's pretty common. They are a baby step towards a potential deal but not the real deal itself. You're interested, but you need to know more about the project before you decide if you want to submit a PO or not.
Even the offer amount can change. Li can terminate the option based on DD and then submit a PO with all new terms.
No one is saying this is a bad situation. But it is not a sale. That's not being negative, that's just the real legal status.
