Pete, Supercub MD is correct. Buckling theory is all about exploiting offsets from straight. Here's more than you'd ever want to know about that! https://www.continuummechanics.org/columnbuckling.html
Folks sometimes make the mistake of thinking that a single reinforcing tube intersecting a column mid-span effectively shortens the length of the column. It can a little bit, based on it's own resistance to cantilevered bending, however the assumption ignores the potential for buckling perpendicular to the plane formed by the original tube and the reinforcing tube.
Bottom line, it's not as simple as it may first appear.
