[neutron][ovn] N/S traffic that needs SNAT (without floating IPs) will always pass through the centralized gateway nodes

Hi,

I read "N/S traffic that needs SNAT (without floating IPs) will always
pass through the centralized gateway nodes," in [1].

Why is that? Is SNAT on each compute node not supported by OVN,
or it's about ML2 driver or provisioning?

Thanks!
Tony
