~/.bashrc is only sourced at the beginning of each interactive non-login
shell (and, one hopes, also from your ~/.bash_profile for interactive
login shells).

PS1 is interpreted *every* time a shell prompt is displayed.

So, a single echo in ~/.bashrc does not serve the same purpose as the PS1
setting.  Most people who put xterm title bar stuff in PS1 do so because
it includes $PWD and they want $PWD to show in the title bar.

As Chet said, the correct fix is to put \[ ... \] in PS1 around all
the characters that don't move the cursor within the terminal -- e.g.
an xterm title bar change command.
