This is incorrect. RMAN needs an incremental level 0, which is a full backup. Incremental level 1 will backup up any changes since the last level 0 or since the last level 1 depending on the incremental type you use. The incremental level 0 is never refreshed. Over time, you can have many incremental backups. You might need to restore the incremental level 0 and then restore all incremental level 1's taken since the level 0. This may take a lot longer than if you had a more recent level 0 backup.

This is fully documented in the Oracle docs. Please have a read through them as they also give you details on how incrementals affect restore opreprations.
