As @SimpleStacker said in the guide: you do not need that "setup process"... Just open a channel with SN node, move out some sats from that channel and done, you have enough for send/receive. Of course, open a good size of the channel to cover your zaps in a certain period.

You will need an inbound channel from all those listed LSPs in Alby ONLY if you want to receive sats from many other sources, not SN. But that is another story and I explain it in other of my guides.
