Active Directory DNS Zone Question (Child Domain zones)

Our forest consists of the root "home.com" and two child domains
"us.home.com" and "eu.home.com". When I look at how the DNS zones are
configured in DNS all three domains are separate meaning when I look in DNS
manager I see

home.com

us.home.com

eu.home.com

The "us" and "eu" zone are *not* delegated from within "home.com".

Working in the lab we did a new install to mimic our domain to test a few
things. However, after getting the test lab up and running the DNS zones are
configured a bit differently. We now have one DNS zone "home.com" and inside
that domain we have two subdomains "us" and "eu".

Question:

How did our production active directory end up having "us" and "eu" as
separate dns zones compared to a new AD install with Windows 2003 having
those domains as subdomains within the forest domain?

Is that because the domain when it was first created was with Windows 2000
and that's how AD would create the zones for child domains?

Thanks

Where your "us" and "eu" zones originally served up by different (local
to the physical location) servers?
