There is only one way for this to make sense:  You did not have mirror-1 in
the first place.  You accidentally added 4  5 without mirroring.  The only
way to fix it is to (a) add redundancy to both 4  5, or (b) destroy and
recreate the pool, and this time be very careful that you mirror 4  5.

An easy way to tell is taking a look at the zpool history command for this pool.
What does that show?
