Stick figure art is helpful as a tool early in the design process to ascertain rough balance, especially in a tree with too many options: too many branches and/or too much foliage. While it may be easy enough to remember which branches you want to keep while looking at a single view, retaining that much data in your mind's eye as you rotate the tree and change the prospective of the prospective front, it is often too much to ask of our limited brains.
Being able to draw four sides and a plan view, then rip up one or all and start over again is an excellent option. It also forces you to choose and allows you to "glue that branch back on". Maybe, only those who have cut the wrong branch off enough times will appreciate Stick Figures.
