Compare two opening sequences - Footsteps and Passenger seat

Both of the sequences include non-diegetic melody's however, 'Passenger seat' has more of a mysterious sense to it. The major difference between the two is that one is meant to be fully understood and the other is meant to be confusing and intriguing. 'Footsteps' has a clear storyline of a young boy growing up and following in his fathers footsteps by joining the military however, 'Passenger seat' is very unclear as the time changes between shots and repeats. This technique of short duration shots and change in time is to confuse the audience.
