+ or X Rear fins??

Notice the folding rear fins and fact that they are at 45 degrees X relative to the intake.

But clearly the rear fins r "+"
Now provided that former missile is oldy with respect to the latter one; I am confused at this
A design progression where the "x" fins didn't work out so they changed to non-folding "+" fins which probably give more range (less drag?, less weight?) but take up more space?
