Will these powercli commands wait to happen or will they execute at the same time?

I have a simple script to move (Svmotion) some VMs - eg;

Get-VM “MyVM1“ |Move-VM -datastore (Get-datastore “MyDatastore1“)
Get-VM “MyVM2“ |Move-VM -datastore (Get-datastore “MyDatastore2“)
Get-VM “MyVM3“ |Move-VM -datastore (Get-datastore “MyDatastore3“)
Get-VM “MyVM4“ |Move-VM -datastore (Get-datastore “MyDatastore4“)

use background jobs:
$vm_list = "vm1","vm2","vm3"
$ds_list = "ds1","ds2","ds3"

for($i=0;$i<$vm.list.Length;$i++)
  # Define what each job does
  $ScriptBlock = {
Get-VM $vm_list[$i] |Move-VM -datastore (Get-datastore $ds_list[$i])
Start-Sleep 60
  }

  # Execute the jobs in parallel
  Start-Job $ScriptBlock
}

Get-Job

# Wait for it all to complete
While (Get-Job -State "Running")
{
  Start-Sleep 10
}

# Getting the information back from the jobs
Get-Job | Receive-Job

@sedgwick - when you work with jobs, are those jobs processed by the local machine, or the remote machines? If by remote machines, do they have to have powershell? same version of powershell?
