It doesn't do that for me. From man bash:
An interactive shell is one started without non-option arguments and
without the -c option whose standard input and output are both con-
nected to terminals (as determined by isatty(3)), or one started with
the -i option. PS1 is set and $- includes i if bash is interactive,
allowing a shell script or a startup file to test this state.
And on my system:
imadev:~$ ssh localhost 'echo $-'
wooledg@localhost's password:
hBc
imadev:~$ ssh localhost 'echo $PS1'
wooledg@localhost's password:
(That's a blank line after the password prompt.)

OpenSSH 3.9p1 for me, on HP-UX 10.20, with bash 2.05b.
