Commentary
UEW considers the Ugric etymology uncertain, seemingly due to semantic reasons. The semantic difference between the Hungarian and the Ob-Ugric forms is notable (UEW presents a possible chain of semantic development: 'gehen' → 'auf der Spur folgen' → 'verfolgen'), and the connection is also phonologically irregular. UEW's reconstruction with *jä- would be impossible for Hungarian ü-, and and the assumed Ob-Ugric cognates do not point to Proto-Ugric *ä.
The Ob-Ugric words are related (both Honti 1982 and Zhivlov 2006 consider them cognates), and Aikio (2015a: 8) has shown that they have a Uralic etymology, reflectings Proto-Uralic *elä- 'to live'. As this etymology presents no phonological difficulties, it is clearly better than the Ugric etymology which should be rejected.
UEW mentions a possible connection of üldöz to Hungarian öl that reflects Proto-Uralic *widə- 'kill' (UEW *weδɜ-). This etymological connection is uncertain, and the different vocalism would point to the forms originating in different Hungarian dialects; further research on this is needed.
Conclusion
The Ugric etymology is irregular and should be rejected.
