They instantly see the e3xh6 and see that queen hits the same diagonal, means this is protected. also they can SEE that Rd1-d3-g3 works when pawn f3-f4. so you have 3 tracks: e3-h6; d1-d3-g3; f3-f4. a trajectorie for me is not a track, it is the geometrical move ! not a legal move on board. e.g. Rd1-g8 is a trajectorie (King g8. R captures King means that you have 2 points: starting point is d1 and wished ending point is g8), the search has the job to fill those trajectories with moves, and in the right order.
