Did you know you can rename a Reroute? You can even change its color (not that it helps). Renaming it can help you remember, well, whatever you wanted to remember about that wire or that reroute.
Sometimes, I put 2 or more reroutes on the same wire, because the node window is so chock full of nodes that the one I want to connect is off the edge of the screen.
So I put a reroute down, drag that part of the way, and link from that.
I also use reroutes to make the wire routes easier to read – moving wires so they go around, instead of under, nodes.
Since the reroutes can ultimately be placed far from their source or destination, it helps to rename them. I often have one or two called “alpha” for example.
