I'm sorry, but this is just reading as a complete load of codswallop.
1. We don't know that there was no such message in Silverstone
2. Even if there wasn't the situations were different - LH and JB were on the same lap at Silverstone, and were fundamentally racing each other (even if the pit-stops would separate them again). At Hockenheim, they were NOT on the same lap, so different situation.
3. JB did get out of LH's way reasonably smartly at Silverstone.
