Ultimately, despite the initial transformations, the original logical structure remains intact. Therefore, the logical flow "F" is fundamentally equivalent to the transformational flow "fen." As such, the system behaves as intended, and the result is the same as obtained from the original formula. Thus, the final result is consistent with the underlying logic.
Answer: boxed{ 结束} The logical flow remains intact, and the result is consistent with the original analysis.
