Tessellation has noticeable difference between adding a Static Mesh and Painting with Foliage

Adding a static mesh to a scene has different tessellation than when painting the same mesh with the foliage brush.

1. Open a new project in 4.9.1
2. Add a sphere to the scene by dragging it from the content browser.
3. Add the same sphere mesh from the content browser to the foliage tool.
4. Paint a sphere next to the the first one
5. Go to wireframe view

Expected: Same tessellation and wireframe
Result : Different calculation of tessellation between spheres
