It doesn't hide. It makes them happen first and, here's the important bit, closes their scope quickly.
The scope is irrelevant it’s a single function class as presented. It was a single method that they broke out “to hide the ifs”. Then they just used compiler specialties to remove the word ‘if’ from the assignments. The comparisons are still there and depending on the execution path those constants may not be so constant during runtime.
