What is proper use of `break labelid`?

I am seeing some inconsistency in the documentation for use of breaking to
labels.

This indicates that groovy works similar to fortran, goto label.
https://groovy-lang.org/semantics.html#_labeled_statements

for (int j=0;j<i;j++) {
   println "j=$j"
   if (j == 5) { break exit }}exit: println "i=$i"


In other places it sounds more like java.

outerLoop:for (...) {
    for (...) {
        if (...) {
            break outerLoop;
        }
    }
}
