Here's a quote from an eBay auction for a DeRosa:
Main frame is Columbus, while fork is Reynolds 531.
The seller said that's the way DeRosa made them because
Reynolds made "better forks."

Just the opposite of the sometimes Masi practice of using Reynolds main triangle with Columbus forks mentioned by some other posters.
Maybe Ugo and Faliero didn't like each other either? ;^)
