It may just be me, but I found the easiest way to understand nets was from the commonest one: "GND" - the reason for naming them is you can have things connected in your layout which you don't have to show in the schematic (and ground, again, is a great example of why you might want to do that).

Either of these nets might branch to yet another pin and that would still be on that respective net. An entire board will have many nets. Starting a new trace and connecting it to an existing net will require you to specify the net number you are connecting to. This can be determined by puting the cursor on the intended net and clicking and inspecting properties of that net .. or it might be shown somewhere on the screen for that selected net. ummmm hope this helps.
