To me, if it's a P-35-pattern pistol it's a Hi Power, whether made by FN, FEG, Inglis or Fabrica Militar. A Browning Hi Power is an FN-made P-35 rollmarked with the Browning name and marketed by FN, mostly in this country, under the Browning name.
As for the FEG being a 3rd-gen S&W meets Hi Power, not true, at least not altogether. The earlier FEGs, known most often as the FEG PJK-9HP, is an exact clone, all-interchangeable copy of the FN Hi Power. FEGs later introduced changes, eventually adopting a version of the S&W lockup system. These, obviously, are significantly different, although some people still refer to them as Hi Powers. Which they aren't, since they're not P-35 pattern pistols.
The "Utah" address is part of the Browning marketing. The Browning name has long been owned by FN (Fabrique Nationale) of Belgium. They manufacture all Hi Powers marketed under the FN name or under Browning. Most sold in the U.S. are marketed as Brownings because the name sells better here. They sell the P-35 under their own FN name in the rest of the world. The Utah-addressed guns have nothing whatsoever to do with FEG.
