Apps that are already installed on the device before isolated_storage feature is enabled will be granted MOUNT_EXTERNAL_LEGACY mode. In this mode, /mnt/runtime/write will be mounted at /storage giving them same level of access as in P. A new mount directory /mnt/runtime/full is also created which will be used for mounting at /storage for apps started with MOUNT_EXTERNAL_FULL mode. This will allow apps with WRITE_MEDIA_STORAGE permission to read/write anywhere on the secondary devices without needing to bypass sdcardfs.
