dalvik - How shared processes are working under the hood in Android?

Question

As far as I know even android app runs on its own instance of VM and only one VM per process is allowed. On the other hand official android doc says

You can also set android:process so that components of different applications run in the same process—provided that the applications share the same Linux user ID and are signed with the same certificates.

So, basically this means that components of different apps may run in the same process, but how is this possible if each app should have its own instance of VM and only one VM per process is allowed ? So, can somebody explain please how this thing works under the hood?
