Spanning Tree Load Balancing

I was asked in one of the interviews about Spanning Tree Load Balancing. Initially, I don't get what the interviewer is trying to ask me. I was thinking after the interview, then I assume what he was trying to ask is as below ???

For example :

CORESWITCH01
--------------------
!
spanning-tree mode rapid-pvst
spanning-tree extend system-id
spanning-tree vlan 10,30,50,70 priority 16384
spanning-tree vlan 20,40,60,80 priority 8192
!

CORESWITCH02
--------------------
!
spanning-tree mode rapid-pvst
spanning-tree extend system-id
spanning-tree vlan 10,30,50,70 priority 8192
spanning-tree vlan 20,40,60,80 priority 16384
!

    Hi!
    Someone asked me similar question. In my opinion they meant to set up different root bridge for deffernet vlans so we can use alternative paths for multiple vlans. In this case we will have paths that are blocked for one vlan but it will be open for different.

    Best regars.
