Xbox repair center and UPS distribution hub in the same building?

So I sent in my Xbox to Microsoft for my RROD, and missing my xbox dearly; decided to research everything about where it was going, and how things work once it got there; and came across this:

The address for the UPS hub in Mesquite, TX (Where the Xbox Repair Center also is) is:

4200 Samuell Blvd, Mesquite, TX 75149

While the address for the Microsoft Xbox Repair Center is:

4250 Samuell Blvd, Mesquite, TX 75149

Which leads me to believe they are both in the same building complex. However, I was wondering if anyone knows this to be true for sure? I tried looking at the entrance on Google Maps, and Google street view and while I see a UPS logo, I don't see an Xbox Logo, or Microsoft logo. So is there something I'm not seeing?

I am guessing they are two seperate building, which are near eachother. They are at least on the same block.

Interesting find. It's amazing what we can do when we are bored:)
