In our case, the coordinate axes $(t,x)$ rotates with $45°$ to $(u,v)$ and coincides with null lines. i.e...." is problematic. From the diagram, $t$ to $u$ is a clockwise rotation of $45$ degrees. But $x$ to $v$ is a counterclockwise rotation of $135$ degrees. Is one of the labels misplaced?

Hi Tom Capizzi, thank you for pointing out the typo. I replaced $(t, x)$ by $(x, t)$.
