Never heard of Right Orthogonal, and left Orthogonal,
maybe they mean right and left circular...

There is some info about cross yagis here.

The high power five relay solution on "simple switching" link 
is the system I was using for nearly 10 years on the TX side. 
It allows H,V,+45 linear,-45 linear, left circular and right 
circular.

On the receive side I used continous polarisation rotation
with schottky diodes and a varicap phase shifter for several
years, but after that I used stereo receivers which is the
ultimate solution with zero faraday loss always (on the Rx 
side.)
