Well to answer your question the reverse has to also be true for the model to work. If you look at the diagram it clearly shows arrows pointing both ways which suggests that the cpu can access gpu cache. Like I said before that black link probably has to do with how the cpu is managing the cache and not using it.

The diagram show you can access in both direction but only highlights the CPU cache coehency but there a lot of chance to you be right... it is more probable.

The reason they highlighted that the gpu can can access cpu cache has to do with the fact that there are more applications to letting the gpu access the result of what the cpu computed.
