Subject: Using the same variable for an array and an iterator

I've just started learning Ruby and am going through a few tutorials.
Right now I'm playing around with arrays and am getting a strange
error.  I am creating an array named 'x' and creating an iterator
named x as well.  Now I know that this isn't good practice but I'm
getting a strange error.  The first time I iterate through the entire
array, simply displaying the contents of the array, I don't get an
error at all.  If I immediately run the iteration again I get a
NoMethodError and am trying to figure out why.  Here's a screenshot

Like I said, I know that this is bad practice, but I'm curious as to
what is causing this error only after the first go through.
