The Linux version has two columns; ever wonder escape (0x1b) visualizes as ^[? because it's a single bit off the actual character "["; all the control characters are; they're visualized by essentially flipping a single bit, and displaying ^ + that letter. This was the point of TFA.
The author's four column layout also makes the 1-bit difference between upper and lower case ASCII readily apparent, which the Linux man page regrettably does not.
