No, that's incorrect. Launch and terminate all you want. If you
reserve two instances, and run an average of three, your average bill
will be for the cost of two reserved instances and one on-demand
instance. There's no designator for whether an instance is reserved or
Instances (reserved or otherwise) are built for failure. Termination
is an expected (if not normal) event.
You can't pick which instance is reserved and which isn't. It just
shows up on your bill.
