American Express Membership Rewards - Dumb question regarding refunds after statement closes

I'm pretty sure I've got this in order but am just making sure it's been a long day!

For example if I have $19k in spend in one month, $15k of which is on one item so my statement closes at $19k. If I get the $15k item refunded before my payment is due it would just show up as if it were a credit/payment to the account, and I would only be required to stump up $4k to balance it?

Correct? Wasn't sure if a refund would show up the same way as a Computer Payment does when I pay online for example...

Correct - but I would suggest keeping a very close eye on your balance online.

Thanks ^ Do I need to keep a close eye for it showing up or being 'processed' correctly?

Just to make sure that the credit actually posts. If the credit doesn't post by the time month 2 closes you're still on the hook for the payment.
