And they do that to have a carbon class frame, in terms of weight, made out of titanium. 3/2.5 except for the seat stays and I think BB shell.
I think 'in general', ti tubes are butted to save weight and perhaps to have thicker butts when the welders cannot comfortably tolerate welding thin walled, straight gauge ti tubes. IMHO.
