The idea is to call the institution back, often customer service, or log in to your account and check for alerts or messages. If customer support knows nothing about the contact attempt, I presume it's not legitimate.

And I'm saying that even if the customer support knows about the call, that doesn't mean that the next call you get in 2m from the bank is legitimate.
In all cases, anyone reaching out to you from your bank should be treated as not legitimate. The only way to do this is to call the bank yourself, and get put through to the person who wants to talk to you.
Any other way including the way you said you'd do it is vulnerable to phishing.
You don't call the bank, check whether it's legitimate, then wait for them to call you again. You call, confirm that they were attempting to contact you, then complete the issue on that same call.
You're not wrong about the incoming calls, but I can't figure out who you're replying to. Nobody above you in the thread seems to be suggesting that the bank ever call you. And certainly not call again in a short time.

If you call the bank, using a customer service number that's already known to you, either they will say there's an issue with your account or they won't. So calling them does tell you, indirectly, whether the previous call (that you hung up on and gave no information to) was legitimate or not. But more importantly, it tells you, regardless of the status of the previous call, whether or not there is an issue with your account, and that's what you care about.
Note that you never have the bank call you back in this scenario. You call them, and that's it. You don't call them and ask them to call you back.
