thickness of the tube is created while the metal is still in its
pre-rolled, sheet form.

That makes perfect sense. Since seamed tubing is made from flat stock, its wall thickness is very consistent all the way around. Mandrel drawn tubing is much more likely to have the I.D. eccentric with the O.D, especially as the wall gets thinner.
