Results depending on evaluation orderby fishy (Pilgrim)

fishy has asked for the
wisdom of the Perl Monks concerning the following question:
I was trying the code from Okay! What!?!?!?

Using eval on the second sample code:
So, I got odd results depending on the order of the operands and right results on evaluating.
How can that be?
