Since this thread got bumped, I'd just like to point out that you should never have to do this technique.
This tutorial shows how to "fix" a bake from highpoly geometry, and if you're baking it correctly then you should never run into this issue. This issue will only show up if you delete your mirrored geometry before baking. The issue does not show up if you correctly bake your whole model with the duplicate UVs offset by a unit.
