If URL matches the pattern of more than one redirect action only the last one is ever tried, others are ignored i.e. if the following actions are defined in this particular order:
and we are opening example.com/something it is not redirected and all we get in the log is
Redirect: pcrs command "s!anything!anything-at-all" didn't change http://example.com/something
The only way I found to make the first action work is to remove the second one.
