-  1. the Pods located on those nodes do not impact `maxSkew` calculation - in the above example, suppose "node1" does not have label "zone", then the 2 Pods will be disregarded, hence the incomingPod will be scheduled into "zoneA".

   2. the incoming Pod has no chances to be scheduled onto this kind of nodes - in the above example, suppose a "node5" carrying label `{zone-typo: zoneC}` joins the cluster, it will be bypassed due to the absence of label key "zone".
 
-- Be aware of what will happen if the incomingPod’s `topologySpreadConstraints[*].labelSelector` doesn’t match its own labels. In the above example, if we remove the incoming Pod’s labels, it can still be placed onto "zoneB" since the constraints are still satisfied. However, after the placement, the degree of imbalance of the cluster remains unchanged - it’s still zoneA having 2 Pods which hold label {foo:bar}, and zoneB having 1 Pod which holds label {foo:bar}. So if this is not what you expect, we recommend the workload’s `topologySpreadConstraints[*].labelSelector` to match its own labels.
