Luckily I had 567 and was completely oblivious to the alternative before I came here for help with the phrase. I nearly started to change it all but spotted the phrase just in the nick of time. A pleasant distraction from a frustrating England performance and a difficulty level I am happy with as my personal Listener baseline.
I agree that the phrase does not actually suggest any further action is needed unless you have the wrong subject.
Not quite sure why 'their' is significant but maybe my grammar is a bit weak.
