Of course. I have already said it was an "umbrella term" to which amacilin picked one
The owner of private key can create several different valid signatures for the same data needed to sign.
This is also "malleability" and I told you about it ( ...by the person who knows the secret... )
The biggest advantage of segwit is that the txid would not change with different signatures
and can be calculated *before* signing the transaction
