This value indicates the depth in the UCS organizational hierarchy (root, sub-organization, etc.) at which this qualifier's defining policy was actually resolved for the object reporting it. It matters because UCS lets sub-organizations override or inherit qualification policies from their parent org, so this number tells an admin whether the rule in effect came from the top-level org or from a more specific org further down the tree. A PolicyLevel of 0 typically means the qualifier was resolved directly at the root organization rather than inherited through several nested suborgs.
