Here's a couple of pics of two trees on a property that I got a call about last fall. Both eucalyptus, but different varieties.
The one at the front of the property was topped and left with regrowth gone wild. To understand the size, the trunk is as wide as my mid-size SUV, the vertical stems at the crotch are 30" diameter and the overall height is somewhere in the 100ish foot range and is just as wide. So, each of these regrowth sprouts turned into trees on top of one massive stump. It was an effing hot mess. These types require a crane to clean up and the bill is massive. None of the verticals were straight either. They all had significant lean. Picking limbs with the crane isn't much of an option as there's no place to set them down, and of course there's powerlines, a house below and a shed with antique cars under the tree.
The second is a tree that was never topped, but instead was left with a main stem intact. The first tree is a repeat offender for dropping limbs, whereas the second isn't, except for dead stuff which could be avoided with annual TLC.

This one does have a big fork near the center of the stem, but it appears natural to me.
