Problem with Omniverse Spheres

While working with USD, Python and Omniverse I ran across the fact that spheres are not accurately displayed (sphere from USD, not from a DCC)
Below you see a USD stack of spheres, unit 1 radius (default), default position - note the gap.
Technically they should be touching as on the right (output USD file from Houdini). The middle set is the rotated version in USD so in that axis they work correctly. Something to note so you do not get caught off guard. Cubes work fine - a good example of geometry approximation.
The python code to generate the usd file:
- spheres - very simple (to be optimized later)
- spheres
rotated
- cubes were done in a similar fashion.
