Hello there, 
    I think Roby's logic is right.  Oliver's suggestion makes both results wrong -- t[[1,1]] should not be set to 1. 
    The rule ("TableCompileLength" -> 1) is not documented.  Span "1;;0" is not documented either.  
    It's not safe to use something that is not documented.
  
    You may want to invent your own version of Set[] for matrices.
