Hi & welcome, Aa2!
TY for tagging me, Rick. I don't have much to add to what's already been said. Agree, the lollipop appearance is normal for an older specimen. These trees lose their lower leaves as the trunk becomes woody. Beheading is the usual procedure for one that's too tall. This can result in 2 stems growing from the stump, but not always. New growth usually comes in right near where the cut was made. Putting the cut-off top in the same pot can get things started toward a clump look.
I've also been nicking trunks (of D. fragrans and other species) over the past year or so but it hasn't produced any results yet.
