What you have described is crown reduction. And although done carefully and correctly it is not the preferred option. We studied some beautiful work done by meticulous aborists on mature trees, they obviously used a boom truck .... the tree did not recover as well as thinning and some of the really mature trees died ... 6 years later.
We do quite a bit of thinning on our eucs here, a common thing.
Thinning does not involve the reduction of height or spread nor the removal of interior branches to the point of there being none. Imagine following the branch from the trunk union and selectively removing a tributary along the way to the tip and one at the tip. Leaders are left intact.
I'll try and get a pic going, I'll need to scan it etc.
