If you created a RAID array with mdadm, it would work correctly - recovery would
start.

Nope, I've got an identical behaviour if the array is created by mdadm (v3.3).

I have checked it twice with Fedora 19 and mdadm v3.3 and it works.
What OS are you running?

As you can see, I'm confused about ISW vs IMSM.

Are those 2 formats the same thing ?

ISW is a name of Intel metadata used by dmraid and IMSM is a name of Intel metadata used by mdadm, but ISW in dmraid has not been supported and developed for a couple of years, so ISW might be called an old version of IMSM.
