Thank you for the visualization. So, if I currently have a bunch of log paths that are final the channels forks would just expand out vertically, but then a junction could be used to join again for the fallback log path? Embedded log paths would just be a fork off of an existing fork?

Just think about this as a pipeline that can:
1) deliver messages
2) fork to different paths and never join again (=> channel / log statement)
3) fork to different paths and then be joined again (=> junction)
4) at every fork, the message is cloned.
+-- channel1 ---- destination
+-- channel 2----+ +---- destination

Channels are like individual if (without else) statements.
Junctions are channel containers, all channels being connected downstream.
