Yes, you're right. The purpose of setting two different cpusets is to 
simulate the scenario of two VMs.

each cpuset is a VM.

For example, the VM configuration is as follows:

<domain type='kvm' id='12676'>
  <name>master</name>
  <vcpu placement='static' cpuset='0-3,80-83'>8</vcpu>
  <iothreads>1</iothreads>
  <iothreadids>
    <iothread id='1'/>
  </iothreadids>
  <cputune>
    <vcpupin vcpu='0' cpuset='0-3,80-83'/>
    <vcpupin vcpu='1' cpuset='0-3,80-83'/>
    <vcpupin vcpu='2' cpuset='0-3,80-83'/>
    <vcpupin vcpu='3' cpuset='0-3,80-83'/>
    <vcpupin vcpu='4' cpuset='0-3,80-83'/>
    <vcpupin vcpu='5' cpuset='0-3,80-83'/>
    <vcpupin vcpu='6' cpuset='0-3,80-83'/>
    <vcpupin vcpu='7' cpuset='0-3,80-83'/>
    <emulatorpin cpuset='0-79'/>
  </cputune>
  <numatune>
    <memory mode='strict' nodeset='0'/>
    <memnode cellid='0' mode='strict' nodeset='0'/>
  </numatune>
