A not very elegant fix (but it works) is to specify the right axis
label as an -r1title()-, see example
*---------------- begin example ------------------
sysuse auto, clear
lab val rep
collapse (mean) mpg weight, by(rep for)
tw (line mpg rep,yaxis(1)) ///
( line weight rep, yaxis(2) ), ///
by(for, r1title("weight")) ytitle("mpg",axis(1))
*------------------ end example ------------------
