Think about the order of execution when you have a subroutine executing as an argument to another subroutine. If you have a sub that is expecting an array as argument, and instead you give it a sub that returns an array, like this:

sub1(sub2());

sub sub1 {
  my @array = @_;
  ...
}

sub sub2 {
  ...
  return @arr;
}

In what order do you expect them to be executed? I think this is what is happening here, the catch is being executed first since it is an argument to try.
