Does account delete, delete the associated SPNs as well?

Sorry for what is probably a dumb question, but when you have an SPN created like the following example:

setspn.exe -S MSSQLSvc/hostabc:1433 DOMAIN\sql_service_account

If the "DOMAIN\sql_service_account" account is deleted, is the SPN also deleted automatically?  Or when deleting an account, is it better to delete the SPNs associated to the account first and then remove the account?

Thanks!
