I don't know, DPC shows us at the start (and a few other times) that this is MC from sometime in the future telling us his story (which doesn't have to be all that far, we could catch up to "real time" in like episode 12 where's he's fucked everything up and then go and try and salvage what we can or something like that), but it's really not done well if that's what it's supposed to be. We clearly see things MC couldn't possibly know. Now there is a really simple explanation for that, MC could just be making shit up as he goes, but there is no indication whatsoever that he is going for unreliable narrator type of story.
There are other ways you could exploit that type of narration, i.e. bring another narrator in and show a different view of a particular event (people remember same things differently as we know), but we haven't seen any of that either.
DPC is a great writer and maybe he plans to actually do something with this in the future, but I'm leaning more toward the fact that he just thought it sounded cool to add those lines and went with it. He has ignored logic and flow of the story in certain parts in favor of stupid drama after all.
