This Has Been Bothering me A Little

Okay, so you guys know the "In Upendi" scene, right? Of course you do. So this little part has been bothering me. Why? Because it's confusing! It's night, then it's sunset, then it's night all over again! What gives! I have some proof for ya, too.
Night

Sunset

Night Again!

And yes, I know for a fact that it's SunSET not SunRISE. They said "Good Night" not "Good Morning" so it's not Sunrise. Wanna help me out on this little confusion?
