You're still naming things, they're just things in a computer that you have to carefully specify so that they behave like their real-world referents within your model (also in a computer.)
'Morning'/'Evening' star won't matter until it does - and if it were something that wouldn't ever matter, you probably wouldn't have input it.
But the framework is completely different. In nature, we must have an inductive framework. We will observe phenomena, and name. With computers, we are doing something very different. The framework is deductive, thus we do not name, we define.
With naming, we can be wrong, because of the inherent negative knowledge of our framework. That is, in science, we can only prove with certainty that things aren't the case, not that things are. This is Karl Popper thesis.
With defining, we cannot be wrong about things, we have the ability to have perfect knowledge, so the things we are referring to are defined to be such, we simply cannot be wrong about their identity and structure.
