Schumacher appeared to cut across the Red Bull of Sebastian Vettel, and the pair narrowly avoided a collision.
The FIA stewards determined that Schumacher was not guilty of doing anything naughty, and the explanation is an interesting one.
According to my source, Red Bull arrived in the stewards office stating that Schumacher should not be issued with any penalty, as he was not to blame for the incident. Instead, Vettel had been advised that his strategy was to do the opposite of whatever Schumacher did: pit if the Mercedes driver carried on, or carry on if he'd elected to pit.
That's why the Red Bull crew were out in the pit lane.
So Vettel had been looking to pit because Schumacher was on his left, but the Mercedes man flicked to the right and into the pits, causing the confusion that Vettel referred to in the press conference.
Because both teams were open with the stewards about the incident, neither was penalised.
