The difference is with regards to how things are organized, on top of eliminating potential redundancies, or irrelevancies.

Comic kaiju for example, has a wide stroking definition. The MonsterVerse Godzilla could be considered a comic kaiju due to his presence in Godzilla: Awakening. The same is said for the Godzilla from Godzilla in Hell, and every kaiju involved with it. However, the MonsterVerse Godzilla has nothing to do with Godzilla in Hell, just like Rulers of Earth doesn't have anything to do with the prior two. Being specific in our categorization eliminates having off-topic creatures come up in categories.

You could somewhat compare it to how we organize movies by decade, rather than going "movies released in the 1900s". As a 1954 film like Godzilla will most likely have next to no relevance to that of a film released in 1999, but will have more relevance to a film released in say, 1955, like with Godzilla Raids Again.

It's all about being specific enough to have the core content be relevant to each other in the category, but not to the point where only a minute amount of pages would fit in.
