For raw text completion I agree with you that it's a bit discordant. IMO text completion prompts work better when you use more of a first-person, here-is-the-beginning-of-some-transcript style.
The OpenAI chat completion endpoint encourages the second-person prompting you describe, so that could be why you see it a lot. My understanding is that a transformation is applied to the user input prompts before being fed to the underlying model, so it's possible that the model receives a more natural transcription-style prompt.
