Why did he set all three columns to a flex basis of 0?
Wouldn't that mean they don't take up any space on the main axis?

The "flex-basis"acts as a minimum size.
Also, when set to 0, the extra space around the content isn't factored in. If set to auto (the default setting), the extra space is distributed based on its "flex-grow" value.
