The 90 degree separation does prevent interaction of the antenna patterns. All that means is that the line lengths to the combiner can be random. However, any structure located 90 degrees away will cause multipath. Most adaptive equalizers need a bit more signal to decode the 8 VSB signal when there is multipath.
The suggestion of an A/B switch is intended to reduce multipath and eliminate the loss of the combiner
