I remember that route balancing has an option to perform per packet balancing and not per connection. If that were to work, then route cache would not be used IMHO. Per packet balancing is normally not done as it would break connections especially in NAT'ted scenario.

To quote the man page for ip, it looks like the balancing is not per packet as you indicate, but rather per-flow.

"""equalize - allow packet by packet randomization on multipath routes. Without this modifier, the route will be frozen to one selected nexthop, so that load splitting will only occur on per-flow base. equalize only works if the kernel is patched."""
