In addition to what the others have said I also belive it to be a matter of programming "style". One could have easily stated the example as this: 
foreach (@example) {
   $unfeasibly_long_variable_name_I_should_know_better_really 
    += $why_do_people_not_learn_to_break_lines / $_;
   }

This way - the code still remains readable, maintainable without needing to "figure out" where things begin and end. So monks that post may consider this as an alternative to "run-on" statements. This of course dos not apply to the obfuscated code.
