No, it does not imply to do any masquerading and the guide is not referring
to NAT in any way for the load balancer.
The NAT should be done by the backends in the uplink farms case, which are
the routers or firewalls with direct internet access with public IP.
Also, the guide is not saying anything about the public IP address in the
load balancer and is absolutely a bad idea.

The guide is just describing the way to do load balancing between uplink
lines for which we've to create 3 different subnets through 3 different
network interfaces in the load balancer and creating a balancer routing
gateway in it. Also, maybe some rules in the backends or firewalls should
be included to detect the client subnet as a local network.
Please, let me know which part of the guide is confusing for you.
