Blink +5v ? Answered

In the blink hookup instructions, the first wire hooked up is the red one from 5v to the red bus, then nothing is connected to it. Did I miss something? Why was it in the instructions but it wasn't used? I removed the 1st red wire and the light still blinked.

From the lesson: "This is a common configuration you will use again and again, and should be your go-to setup for new breadboards, even if you aren't using both buses immediately. Circuits in this lesson will connect to the ground bus, and in the next lesson you'll use some components that will connect to the 5V power bus."
