Of course (he mentions it) he could lit up more than one at a time, but probably this will soon draw too much power. Amplifier stage would be necessary then (and a more complex one than for normal matrix multiplexing), killing the simplicity of the design.

I would have never thought to utilize the input state to control an output. Thats a really interesting way to use the GPIO of a MCU.
