Question about pg_wal.tar.gz generated by pg_basebackup

Hi All,
I am taking backup using pg_basebackup for the purpose of point in time
recovery in case something goes wrong with the data.
The backup generates pg_wal.tar.gz which contains the wal file generated
during the backup.
Is it of any use in the point in time recovery? do i have to archive it?
According to the documentation, any wal files in pg_wal directory has to be
deleted after the base backup is restored and before the recovery starts.
So if i understand it correctly, pg_wal.tar.gz is not required for point in
time recovery...but just want to confirm if my understanding is correct.

My sole purpose of taking the backup is for point in time recovery. I am
not going to use it to create a standby server.

Thanks,
