It is different, unlike Colorado and Wyoming there actually was a vote, he won that vote going away and the delegates were assigned accordingly.
That is simply not true.
The Nevada Republican Party caucus is a closed caucus with eligibility limited to those registered 30 days before the caucus date including 17-year-olds who will be eligible to vote in the November general election. As in most other Republican caucuses, there are two components. First, delegates are elected from the attendees to represent the caucus-goers at the county conventions in March, and they generally announce who they support for President and why they should go to the county convention. Election of delegates is by show of hands. Then, a supporter of each campaign speaks on behalf of their candidate. Finally, a straw poll, called a presidential preference poll, is taken of the individuals in the room. The preference poll is a secret ballot with candidate names printed on them.
Although the news media reports the results of the straw poll and assigns delegates proportionally based on it, in Nevada, it is the county conventions and the state convention which determine who actually goes to the Republican National Convention. Thus, all delegates are unbound until the state convention in April, but they generally represent the preferences expressed by fellow Republicans in the straw poll
