Why do time-travel novels like to say that you're reborn into someone with the same name?

Not all time-travel novels would use this term, but in some novels, there were often situations where one was reborn into a person with the same name because of the following reasons: 1. Increase the tension of the plot: Reincarnating into a person with the same name can make the plot more compact and allow the reader to be more involved in the story. In this way, the author could better show the growth and changes of the characters and enhance the attractiveness of the novel. [2. Prominent character characteristics: Reincarnating into a person with the same name can make the character more distinct.] If the characters still have their own unique personality characteristics and experiences after rebirth, it is easier for readers to resonate with the characters and better understand the theme and meaning of the novel. 3. Increase the cohesiveness of the plot: If the character is reborn and directly transmigrated to another world, the cohesiveness of the plot may be challenged. By reincarnating into a person with the same name, the author could use the previous character experiences and plot clues to better construct a new world and plot line to improve the cohesiveness and legibility of the novel. It should be noted that being reborn into a person with the same name was not necessarily an inevitable choice in the creation of a novel. The author could decide whether it was suitable for this kind of plot arrangement according to his own plot and character creation.
