[erlang-questions] net_adm:localhost() return value for -sname?

The manual says about net_adm:localhost():
"Returns the name of the local host. If Erlang was started with the
-name command line flag, Name is the fully qualified name."

The manual is kind of correct, as at least in my Debian Lenny it gives
the long name in both cases. But to me the wording kind of implies, that
localhost could return the short name, if started with -sname.

:/proj/egse$ erl -name test
Erlang (BEAM) emulator version 5.6.3 [source] [smp:2] [async-threads:0]
[kernel-poll:false]
Eshell V5.6.3  (abort with ^G)
()1> net_adm:localhost().
"adic.fmi.fi"
()2> 

:/proj/egse$ erl -sname test
Erlang (BEAM) emulator version 5.6.3 [source] [smp:2] [async-threads:0]
[kernel-poll:false]
Eshell V5.6.3  (abort with ^G)
()1> net_adm:localhost().
"adic.fmi.fi"

My /etc/hosts
:$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 adic.fmi.fi adic

wondering, what was the intention?
