A very valid point. The aircraft being involved in the attacks on Coventry and Broadsword were A4s, and had been transiting at low level, and I believe that the SHARs were descending from the CAP to engage, so one could probably assume that they were catching them.
They did not reach the first pair before they entered the Sea Dart Zone, and were called off the second pair by Coventry, which from reading between the lines they were a lot closer to than the first.
This is a well know photo of the first pair, Carballo and Rinke, bearing in on Broadsword, taken by a very brave (or foolhardy) matelot.
