The Caloi Lance rode was a re-badged Eddy Merckx. Caloi paid to have their stickers on there, like Huffy did for Andy Hampsten and 7-Eleven.

Lance also rode a Litespeed Blade with Trek stickers on it in 1999 for the time trials.

The pros ride what they are paid to ride, and sometimes they don't really ride it. What they ride should never influence your opinion of the bike.
