A helper method the constructor calls in a loop, after a short circuit or in a conditional expression may not run, so the fields it writes are not definitely assigned after the call. The analysis followed such helpers with the constructor's own assigned set, and a later read of one of those fields used a plain slot. Writes now count only for a call that is the whole statement, a field write's value or a declaration's initializer. The else branch of an if also starts from the capturing fields as they were before the if, so a branch that replaces a closure field leaves the earlier closure tracked on the other path.
