help with relative mode

[Adam Good]

Hi everyone,
Seems like there is a fairly simple solution but I couldn't even  
think of how to search the manual or email archives for what I'm  
looking for.

in the snippet below I'm using \relative mode and defined "one" and  
"two". When I compile i want the second occurrence of "one" to be in  
the same octave as the first occurrence. How can I do this using  
relative mode?

something like:
\octaveshift "down" \one
??

but how would I define that?

%%%%%%%%%%%%%
\version "2.11.33"

one = {c4 d e f g a b c}
two = {d, e f g a b c d}

\relative {
\one
\two
\one
}
%%%%%%%%%%%%%
