Yeah. While the instantaneous power draw is absolutely colossal, the actual energy drained from a battery starting a (healthy!) engine is fairly minimal, and its replaced very quickly by the alternator once it's up and running. Stop/start engines also use the ECU to stop the engine at the right point in the compression cycle for it to fire immediately, without cranking, so there's even less drain. (Even pre-stop/start engines in cars with modern ECUs tend to leave them in a position where they fire almost immediately.)

What kills batteries is deep discharge cycles. Sipping a bit of juice to start an engine and replacing it quickly does almost nothing to reduce its lifespan.
