In the event OP's native language is not English, it might just be 
unfortunate word choice rather than a criticism of the function's value.

I am fairly certain David K. wrote \after back in the 2.19 era, so there 
should be no particular need to run 2.24.  I found this version on an 
old thread:

%%%%
after =
#(define-music-function (t e m) (ly:duration? ly:music? ly:music?)
  #{
    \context Bottom <<
      #m
      { \skip $t <> -\tweak extra-spacing-width #empty-interval $e }
    >>
  #})
%%%%
