I guess this is in case someone do something as replacing two 500GB drives with two 1TB drives and then wants to replace those with new 500GB drives, since setting autoexpand=on is quite simple and for the expansion, irreversible. If you have expanded a VDEV, the only way to shrink it is to backup, reconfigure ZFS and restore.

[zfs-discuss] Replace block devices to increase pool size
Hi! I have a zpool biult up from two vdrives (one mirror and one raidz). The raidz is built up from 4x1TB HDs. When I successively replace each 1TB drive with a 2TB drive will the capacity of the raidz double after the last block device is replaced?

Re: [zfs-discuss] Replace block devices to increase pool size
If autoexpand = on, then yes. zpool get autoexpand pool zpool set autoexpand=on pool The expansion is vdev specific, so if you replaced the mirror first, you'd get that much (the extra 2TB) without touching the raidz.
