This is not universal. Many don’t proactively check, the signature is typically used afterwards when the account owner makes a claim that some action was fraudulent. Some businesses will check to avoid precisely dealing with those claims, but most don’t have to.
And also, legally the mark can be anything and it’s just a convention that it is your name.

So how did they know you were you?
They allowed you to update the signature. They may have been oddly fixated on the signatures matching, but they still verified your identity in some other way.
Or they’re idiots who shouldn’t be in control of other people’s money,

Yes, they verified my ID, but still required my signature.
Most likely due to withdrawing money being bad for the bank.
