Updating the ME and Descriptor region is occasionally needed. Typically once per product. I say this from experience, as I own this on a Sandy Bridge / Ivy bridge product.
The question is what would happen if you update the BIOS region only. The ME is completely independent, but it communicates with host firmware while and after booting. We just don't know if this communication would just continue to work or not and if not what the consequences are.
