From my experience, the massive damper in alternators like the one you described does indeed act like a squirrel cage rotor in asynchronous operation. This is especially true in cases of excitation failure. The damper's primary role is to suppress rotor oscillations and help maintain synchronicity, but in the event of a loss of excitation, it can provide a kind of "fallback" mode of operation. It's not ideal, and efficiency takes a hit, but it's definitely better than a complete system failure or damage to the alternator.
