John Doe, sure, turn off ONLY the rightmost 1-bit.

The point is you can have a situation where you need to turn off the rightmost bit. For example you have an array of LED devices and an 8 bit array controls which devices are on are which are off. And you want to turn off the rightmost device. Then there you have it.

Ps. there shouldn't be any mistakes in the article, i proof read it around 10 times and it took me several full days to write it.
