As long as 1 vdev is striped and not mirrored, that's true.
You can only afford to lose a vdev, if your vdev itself is mirrored.

You could, for example, create 2 vdev's of raidz2, and instead of striping
them together, mirror them.  Then you could lose one of the raidz2's, and
the other half of the mirror is still up.
