It's matching the prefix.  To make it match the string and
only the string you need a $.  Either do

   (pat1$)|(pat2$)| ... |(patN$)

or do

   ((pat1)|(pat2)| ... |(patN))$

If you do the last, don't forget to omit group(1) in
the list of results, or use the non-capturing group
notation, which I believe is (?:  ... ) as in

   (?:(pat1)|(pat2)| ... |(patN))$
