It's totally unimportant in which order you see them in /proc/mdstat.   
It's just the order kernel module detected them.  There's really no  
"first" or "second" device here.  They are equal.  It's just that when  
printing them out, one of them had to be printed out first.  So, they  
are not "reversed" regardless of the output of "cat /proc/mdstat".   
Simply because there no such thing as "reversed" ;-)
