  I believe you got it the other way around.
  Here, the necessary condition for "expressing an emotion" is to be "capable of experiencing."
  CANNOT X, not Y = X -> Y.

  It seems we speak the same?
  
  If artwork's creator incapable of experiencing, then artwork cannot express an emotion.
  
  equals to
  
  If "expressing an emotion" then "capable of experiencing."
  
  And also, how can you know cannot X, not Y means if not Y then cannot X(X-->Y)? I check JY's course and don't find it. Is this one(cannot) in the group 2 means necessary condition?

  Cannot is another way of saying "not," which is a Group 4 (negate necessary) condition.
  
  You're each saying one of the contrapositives of the statement, so you're both correct.

  @JS oops yes you are correct. I misread your translation!

  @Ponyboy, @CJ Shin, JY's example of "cannot" (e.g. You cannot fight crime and run marathons. ) seems to be different from this one.
  
  But it seems still cannot means negate necessary here.
