The long name of the license (licensetpl_long) is mapped to the UsageTerms field - probably because that is the XMP field most related to licensing. Even so, I don't think that choice makes sense since we publish other details of the license (short name, URL) which do not fit into XMP; the field should be called LicenseLongName or something like that.
