Replying to Level 1 movie names?

Wow, im sure a lot of u have realized this but i just came acroos it as i was looking at all the level 1 movies on their site. I never noticed that all the names of their movies correspond to the order they're made(except the first one)...

Shanghai Six- 6th movie by L1
High Five- 5th movie
Forward(4-ward)- 4th movie
level 3- 3rd
second generation- 2nd
Balance- I guess this one works cuz its made by level 1, so the ones already covered.

Just kinda wierd I thought.
