My suspicion is that the desantis’ wanted to fool supporters into going to iowa from out of state, thinking they could vote in the caucuses.
When they got there, and found out they couldn’t vote though, they would be crazy and loyal enough to try to speak and argue other voting caucus goers to support and vote for desantis.
The reason I think that is this article
Ron DeSantis campaign can’t ‘commit’ to pay travel costs for Iowa caucus supporters

The Ron DeSantis campaign is encouraging supporters from around the country to come to Iowa next month for the pivotal caucuses to try to sway locals into backing its candidate.
But in an email to supporters, they’re saying those committed backers need to be prepared to pay their own way.
“Candidates can have surrogates speak on their behalf at caucus night. We have more than 500 caucus locations that we’re looking to fill, and we’d love to have some of Governor DeSantis’ trusted supporters speak on his behalf! It’s an all-hands-on-deck effort!”

Vargo suggests that Iowans will welcome those from elsewhere to be a part of their “very localized process, where neighbors are thrown into a room and vote for their Presidential Nominee.”
