No, this is because you set $PS1 in /etc/profile, but /etc/profile is 
only read when opening a new login shell, su does not open a login 
shell, but just a normal interactive one, if you want bash to set your 
new prompt, either use su - which starts a login shell, or set $PS1 in 
~/.bashrc (you could also source /etc/profile in .bashrc)
