Yes; think about the production line. Imagine they are building these things sequentially, overlapping. Then someone says "Oops, let's change this." You start implementing the revision on the ones already past that point in the build... and integrate it from the start into the ones that haven't yet reached that point.
So, it's reasonable to assume that 505 and 506 are being retrofitted with some changes that are being made to the fleet here (502-504), and 505/506 in Millhaven, but 507+ already got them.
