Sebastian,
There are many reasons why someone would want the DIDs provided by one 
provider and outbound calls to go out via 1,2 3, or more providers.
In one of my installs I have a situation where local calls are placed 
via a local telco switch but LD calls go out via a voip provider.  The 
Local telco has the DID but the LD does not so I have to verify the DIDs 
with the Voip provider(s).
Another case may be for least cost routing.
There are other reasons but you can see that it is not always as simple 
as using the same provider for DID and origination.
Thanks,
John
