That's exactly what I think. If pressure is being put on the flesh during thawing that might explain extra liquid in the package as some people report. It also might compromise the texture. This is the main reason I am taking this step.
Some people claim that the defrosted fish sitting in those "juices" makes it smellier. They were talking about tuna specifically in that case.
Some folks take the fish out of the package and put in on something where any liquid will drain off the fish while defrosting in the fridge instead of remaining in contact with the flesh.
These are precautions worth trying to see if they do improve the quality of the defrosted fish. I haven't taken the extra step of putting the fish on something that can drain away the liquid, but if I'm not happy with my defrosted tuna, I will try that too.
