No, it isn't supposed to be like that, but currently it is.

The easiest approach if to create it with 2 drives missing, and the
extra drive immediately.
This is essentially what mdadm will do when I fix it.

Alternately you can use --assume-clean to tell it that the array is
clean.  It is actually a lie, but it is a harmless lie. Whenever any
data is written to the array, that little part of the array will get
"cleaned". (Note that this isn't true of raid5, only of raid6).
