A 2 pole breaker with handles tied together is not the equivalent to a 2 pole breaker.You‘re likely seeing a 2-pole breaker. That’s how 240v breakers work. It’s two 120v breakers tied together. Completely normal.
Some of the older two pole breakers actually had two handles tied together, but still had an internal common trip mechanism - this is likely what Mikeho has. Modern 2 poles will have only one handle.
It is possible to use handle ties to connect 2 single pole breakers, but those should not be used on 240V loads because when one breaker trips, it won't trip the second pole. A true 2 pole breaker will open both poles even if overcurrent is only detected on one.
