That is described in the parent section:
It is impossible to separate the standard output and standard error
streams of the subprocess, because Emacs normally spawns the subprocess
inside a pseudo-TTY, and a pseudo-TTY has only one output channel. If
you want to keep the output to those streams separate, you should
redirect one of them to a file—for example, by using an appropriate
shell command.
