This in no way implies that it is possible for a submarine to actually launch a second salvo a minute later, does it?
Usually not. Torpedoes are commonly equipped with wire guidance, meaning a submarine can only guide as many torpedoes as it has torpedo tubes at any one time. Thus, even though it may be able to load a second salvo of torpedoes very quickly, unless the torpedoes already in the water switch to autonomous guidance and cut their wires, another salvo cannot be loaded. And at 30 knots, it takes a torpedo a full ten minutes to reach 10,000 yards, so during this time the submarine cannot reload its tubes. There are also concerns about whether or not multiple torpedoes in the water could confuse the submarine's own sonar if it is not properly able to resolve them.
Of course, for many roles (such as attacking carriers), autonomous guidance is preferred, so it is possible to rapidly launch salvos, but usually a submarine's primary goal after firing off the first salvo is to start fleeing.
