Hi, and welcome to the forum. The gentleman you are referring to has chosen to open carry in Condition 2. That is his personal choice and does not reflect either the law or the choices of other members of the forum. (When I am in WI to visit family and friends, and open carry, I carry in Condition 1.)
Having said that, in Utah one must carry Condition 2 in open carry mode, unless one has a Concealed Firearm Permit.
