>My actual question was why are we creating standby control file in primary database ?
If you don't use the primary DB to make the standby control file, what do you use?
What is viable alternative to make the control file?

Because before creating a standby database you have no control file of this standby database and the purpose of standby database is... (third tiùe) to be able to create this standby database.
Do you understand what you read and write: "Note: This step is part of create standby database"?
