It's an inconsistency because the name seems like it was put there intentionally to represent SOMEONE. Since your example above lacks any degree of coherency, here's how you make an inconsistency.
Tom, dike and Harry are all working on a cool new video game. Their boss comes in one day.
"Tom, dike and Harry, take this name Talin. You're all responsible for getting it into the game. We're shipping tomorrow morning so get it done and forward your work to me, I'll make sure it's all compiled into the final product."
Tom, dike and Harry all scurry off to their cubicles. Tom puts an odd reference to Talin as the main character in the manual. He drops dead of a massive heart attack moments after submitting his work.
dike takes a look at the game's character bios and puts an odd reference to Talin as the commander of the Imperial Guards in the game's intro sequence. Just because, he also changes Uriel Septim VII to Uriel Septim IV on one of the intro screens. Why? Because this is the way dike is and this is what dike does.
Because Tom kicked the bucket and dike didn't have access to his work, he doesn't know about Tom's reference to the player character, not that he'd be likely to care. While whistling happily to himself over what is surely a job well done, he submits his work to the boss and clocks out a well-deserved two hours early, leaving Harry all by himself in the office.
After brainstorming in his cubicle all afternoon trying to find the best way to use the name Talin, he quickly settles on an odd reference to someone's (possibly the player character's) father in the class generation sequence. Because Tom is worm food and dike is...well, dike, Harry has no idea Talin has already been used twice for two separate characters. He submits his work and heads out for the day, wondering about the odd smell coming from Tom's cubicle.
Talin was never mentioned again.
When the game ships, no one can say for certain who is named Talin because the programmers and manual writers, through lack of communication, managed to create an inconsistency. Many, many years later, some guy on a forum decided Ocato was the player character. Others argued way harder against this theory than they ought to, considering the evidence they were using was based entirely on an inconsistent naming scheme.
Lurking on the forums, dike came across this particular thread. And dike laughed.
Because for dike, this was amusemant.
