Why was Louis Tomlinson sent home from x factor?

Louis Tomlinson was sent home from "The X Factor" during the auditions in 2009 because he did not initially make it through to the next round as a solo artist. However, Simon Cowell saw potential in him and suggested he be put together with other contestants to form a group, which ultimately became One Direction. This decision significantly altered his career trajectory, leading to their immense success.
