QoS - nesting

Referencing the docs on nesting -

gives an example of nesting, but does not use the same class name in both
policy maps as does the example below.
 
1. What happens if you use the same name for a class to nest a policy when
you used the same name in the policy you are nesting? The example in the
docs uses a different name besides the default "class-default". Does not
seem right but it is passing traffic.
 
   
policy-map VOICE_QoS
 class voice-ethernet
    priority 1000
   set ip dscp ef
 class signaling-ethernet
    bandwidth 20
 class class-default
    fair-queue
     random-detect dscp-based
  
policy-map SHAPE
 class class-default
    shape average 5000000
  service-policy VOICE_QoS
!

 
 
Thanks.
