Right on. In addition, the 45/45 biax is built from 2 layers of
unidirectional glass. This is stronger than a normal weave where the yarn
passes over and under other yarn throughout the material ...this naturally
puts a cutting force across the yarn and consequently unidirectional layers
in biax (etc) can take more tension before failing.

About fiberglass splices.
Payson and Carnell miss an important point. They use plain woven glass
in which half of the fibers run paralell to the seam: a complete waste
of glass and resin.
The proper way to build such a seam is with biaxial 45/45. With that
type of glass, all the fibers work and it also adds a little torsional
strength.
I don't know why that point is not understood. I mentioned it for the
1st time here 12 years ago and designers still specify the wrong type
of glass for splices and stitch and glue seams.
