Yes it is pointing to the same page.

Have you made sure it's matching part of the area? I'm taling testing using a single letter or number. 

I've seen some wonkiness with pattern matching if it goes over a line break. I've been able to pattern match successfully over a line break when testing by cutting and pasting it into the test area and having it NOT work when it runs. To get around this I sometimes export the whole zone to a field and having workflow deal with it. You just end up needing very large fields, and if you are running it in agent you need to put a limiter on the field to make sure it doesn't go too long to fit. I usually use the pattern (?s).{0,499} to trim it (if needed) to a field with a limit of 500. The (?s) changes the . to match either \n or \r as well.
