Yes, but I sincerely doubt router vendors will peek into GENEVE headers. IMO, they'll either use IPv6 flow IDs or look for transport flow context. Even a NVI isn't really flow information, so might not have any bearing on whether a set of packets (with the same NVI) should maintain their relative order.
