Upgrading Executable on the Fly - wrong docs?

After reading the section titled "Upgrading Executable on the Fly" in the
docs (at http://nginx.org/en/docs/control.html) I have an impression the
information given is wrong.
In the first bullet one reads
"Send the HUP signal to the old master process. The old process will start
new worker processes without re-reading the configuration. (...)"
then in the second and third bullet one reads
"When the new master process exits, the old master process will start new
worker processes."

If the old master process already started new worker processes after it had
received the HUP signal then it means it didn't have to wait until the new
master process exited, right? Doesn't this contradict the subsequent
information that the old master process waits with starting new worker
processes until after the new master process exited?
