C'est vrai, ça diffère :)

Sous debian 11 :

$ man apropos | head -n 23
APROPOS(1) Manual pager utils APROPOS(1)
NAME
 apropos - search the manual page names and descriptions
SYNOPSIS
 apropos [-dalv?V] [-e|-w|-r] [-s list] [-m system[,...]] [-M path] [-L locale] [-C file] key‐
 word ...
DESCRIPTION
 Each manual page has a short description available within it. apropos searches the descrip‐
 tions for instances of keyword.
 keyword is usually a regular expression, as if (-r) was used, or may contain wildcards (-w), or
 match the exact keyword (-e). Using these options, it may be necessary to quote the keyword or
 escape (\) the special characters to stop the shell from interpreting them.
 The standard matching rules allow matches to be made against the page name and word boundaries
 in the description.
 The database searched by apropos is updated by the mandb program. Depending on your installa‐
 tion, this may be run by a periodic cron job, or may need to be run manually after new manual
 pages have been installed.

L'important, c'est "...as if (-r) was used..." : c'est l'option par défaut.

$ man whatis | head -n 25
WHATIS(1) Manual pager utils WHATIS(1)
NAME
 whatis - display one-line manual page descriptions
SYNOPSIS
 whatis [-dlv?V] [-r|-w] [-s list] [-m system[,...]] [-M path] [-L locale] [-C file] name ...
DESCRIPTION
 Each manual page has a short description available within it. whatis searches the manual page
 names and displays the manual page descriptions of any name matched.
 name may contain wildcards (-w) or be a regular expression (-r). Using these options, it may
 be necessary to quote the name or escape (\) the special characters to stop the shell from in‐
 terpreting them.
 index databases are used during the search, and are updated by the mandb program. Depending on
 your installation, this may be run by a periodic cron job, or may need to be run manually after
 new manual pages have been installed. To produce an old style text whatis database from the
 relative index database, issue the command:
 whatis -M manpath -w '*' | sort > manpath/whatis
 where manpath is a manual page hierarchy such as /usr/man.
