So the headers determine which disks mirror which disks?

Does that mean that if I ordered my disks correctly on the --create commandline, I could depend on all of the data being ordered the way that some of the data is?  I.e. if I figured out which two disks were mirroring each other, I would know that they'd always mirror each other as long as I didn't update the array metadata in any way?

Thanks.
