Note that the article glances over the first byte of image data which specifies how many bits each pixel occupies and sets it 07, which makes first 128 symbols of the resulting LZW stream byte aligned. This is probably never the case in practice (for the presented images it should be 1 respectively 2).

Someone needs to release bit for bit break downs of common image formats. It’s always fun to draw by hand.

It is mentioned near the end though.
