"The further the submarine descented the more the weight of the submarine increased due to pressure."
How does that work? I thought pressure under water is the same from all directions.

The author was correct, but for the wrong reasons.
The weight of the submarine increased due to the additional mass of water in the ballast tanks. The weight of the submarine increased due to the increase in Earth's gravitation at points nearer the center of mass. The apparent weight increased due to a reduction in buoyancy.
But in no way can you increase the weight of something by squeezing it. (Aside from invented hypotheticals like two gas giant planets wrapped in unbreachable envelopes, lightly touching, without rotation.)
