Sounds like it.

I'd rather have separate VBOs to keep the test focused on one thing
(primitive restart). I really don't have any time now to
investigate/fix the single-vbo + restart bug (it might happen with all
gallium drivers, btw) so the test would just keep failing for the
foreseeable future. I'd rather not leave it in that state.
