The reason why Kindred is considered to be one person

It is because the lore is so limited that gameplay is the only thing that makes up a character. You are playing as Lamb 90% of the time if not 95% of the time and have very limited action with wolf. It is hard to imagine two characters that have a conversation exactly one sentence long and that is it aside from the brief description. Then we have the auditory experience in game that is so limited that most people just end up muting the champion. Because we all love to listen to Corki's sound pollution and Caitlin saying the same thing over and over again until I have to literally kill her at dragon.

"Never one." ~Lamb "Without forgetting the other." ~Wolf

League of legends is still the worst game when it comes to lore and it is pathetic because they make an extreme amount of cash coin yet they refuse to somehow hire somebody to write more than 4 sentences for a lore.
