To the previous answer: however, Andersen had logical logical questions to this version - to which Sherlock had no answer.
Moreover, we still do not know what happened on the roof during the conversation with Moriarty. Once I played a video of Jim's "suicide" scene on slow motion - what do you think? At the moment of falling on his back, he did not even have a pistol in his hands (!). This is hardly an accident :) so there are still a lot of questions
This is covered in the first episode of the third season. Sherlock's brother, Mycroft, Molly, and a group of homeless people from Sherlock's network were in the plan. In front of the building, on the roof of which Sherlock was standing, there was a smaller one-story building, so that Watson could see Sherlock, but could not see that an air cushion was being spread in front of the first house. The cyclist who knocked Watson down was also part of a plan to distract the doctor while Sherlock falls onto a pillow and then that pillow is removed. Sherlock lies down on the sidewalk, assistants put on makeup, spill a bag of blood, and to stop his pulse for a while, Sherlock clamps a small squash ball under his arm.
