GlobalChannels nodes straight from global channels name

I noticed something very peculiar in the “How To Talk To Global Channels” help patch.
Somehow there are nodes reflecting global channels in this patch, “a, b, c, d”.
How were they created? Nothing in the definitions, it’s a bit of a mystery.

did you open the global channel browser?

@sebl yes

@gregsn has already answered this in the Matrix chat, it would be great if he would just copy that answer to here. My opinion is that the example should be changed and this feature should be removed.
