Doesn't this article exactly make that point? Because it shows how JR was split apart, yet the brand logo still makes it appear as if it's a single unified group, doesn't it? Here's the passage I'm referring to:

>'Rail transport in Japan was originally run by Japanese National Railways (JNR). Like many state-owned corporations, it was starting to struggle in the 80s with mounting debt. JNR was losing its advantage over other transport, in both passenger and freight. In the ’80s, the Japanese government began pushing to privatize its state-run monopolies — to reduce the national deficit and improve efficiency across these sectors.'"

The article mentions 'improve efficiency,' and that's the part I was looking at. Then it goes on to explain the strength of the brand logo. So the overall point here is, 'How can something that has been broken apart still appear as one?' And I was simply saying that, despite the inefficiencies in that process, the fact that it still comes across as so stable shows that the branding strategy is good.
