What is the purpose to have these two different API versions?

This is from mplayer manual:

-fixed-vo
      Enforces a fixed video system for multiple files (one
      (un)initialization for all files). Therefore only one
      window will  be  opened for all files.

Most probable interpretation of this by average user: only one window 
will be opened and since user can change window geometry or change 
modes during playback, it will be kept by mplayer until user changes 
mode again just because mplayer _must_ _not_ (according to the manual) 
initialize VO again.
