Maybe. The tendencies that pod parents offer are growing habit and vigor, plant size, temperature tolerance, and just about anything that deals with how a plant grows. IME, flowers tend to be less affected by the difference in pod/pollen parent, except maybe for yellow color (at least in Cattleyas and Oncidiinae).
Backcrossing should not be done randomly. It is done to bring out specific traits present in both parents, or SHOULD be present in the genome of one of the parents based on your knowledge of what the parents do. For example, your primary cross Mem. Violet May produces some very pretty pastels, but on relatively poor stems. You want better stems, so you cross this back to fowliei to get them. Or you want rounder flowers, so you put it back onto godfroyae.
BUT REMEMBER INDEPENDANT ASSORTMENT of the chromosomes. It is not just a good idea, it's the law. Randomness plays a huge role in these crosses. Growing out a bunch of seedlings gives one the opportunity to see not only if anything good turns out, but what traits are dominant, what is bad, what is good, and is it consistent. Given the inescapable fact that Paphs cannot be clone, this idea of a clone that throws good offspring becomes tremendously important (especially to the pot plant industry). You know that every plant (or at least most of them) will have the traits you are looking for. That makes some clones exceptionally valuable. For example, C. Horace 'Maxima' breeds for size and shape, and is recessive for color. But half of the offspring will have cripled flowers. At least you know that before you use it.
