Answer
The examples given are not material things, nor can any information be transmitted by these events.
Work Step by Step
Special relativity says that no material thing can move faster than light. The intersection points named are not things.
Furthermore, there is no energy or information moving faster than light - in other words, these schemes do not provide a way to send a faster-than-light signal from one location to another.
In summary, special relativity bans the transmission of energy, particles or information at speeds greater than the speed of light, c.
These examples do not contradict special relativity.
