The narrator also has a follow up reply to some of the comments.  Not sure if this explains in enough detail to agree with but he might be onto something:

The only way you can understand this is to understand this first: time is a dimension like X, Y, Z (say corresponding to width, height and depth). So, yes, there is a number on the time dimension which corresponds to your location which happens to be in the future, as well as in the past or at this moment. Your past, your now and your future exist in the same way. However this does not mean your future is predetermined. It is very difficult to understand this; perhaps impossible for humans at the moment. Watch my other videos regarding Quantum Mechanics (illusion of distance, rigid objects etc) which will help you develop an intuition about nature of reality. No one fully understands these, so don’t worry if you can’t.

We hope you like the video and feel free to comment with your own theories.
