When performing loop subdivision, maintaining continuity is important for the surface. A paper that talks a little bit about this: http://persson.berkeley.edu/pub/persson06subdiv.pdf

The top right image doesn't really look like one where all the edges have been split. Only one edge in each triangle has been split. Is that the correct interpretation?

I'm not sure what you mean by one edge in each triangle, but every original edge in the previous mesh has been split. We can see there is a new, blue vertex in the center of every original black edge. The blue edges are the new edges added during the splitting process.

This visualization helped me so much in understanding this concept. Breaking down the flip and the split then showing how these two concepts can be used to achieve this practical result is very cool!
