ssh without a command is equivalent to slogin, which starts a login shell
on the remote host. Login shells don't execute ~/.bashrc (and, if so
configured, SYS_BASHRC), so there's usually a line to source it in one of
the login shell startup files (/etc/profile in your case). That's why
it's there, and that's why removing it had the effect you observed.

Well, it's the difference between a login shell and a non-login interactive
shell.
