Auto unsealed with Azure Key Vault but still shows the "Recovery Seal Type" as "shamir"

Have installed Vault on Azure Kubernetes and have configured the auto unseal with Azure Key vault. Initially post the deployment , Vault status returns with Seal type as “azurekeyvault” and sealed as true. Once I have initiated with below command.

kubectl exec -it hashivault-0 -n vault -- vault operator init -recovery-shares=1 -recovery-threshold=1

Post that Seal type is changed as “shamir” but the Vault is accessible and active.

Is this expected behavior or is it not referring to Azure Key vault certificates for unsealing ?

Found it seems to be expected behavior .
