The events that happen to the same observer are in order for the observer moving with the particle using that observer's clock. If, however, you look at distant events in a relativistic setup, then you can't always define an absolute order of events. Some are causally related, i.e. they will come in the same order for all observers, but some are not, they can't influence each other and they can show in different order depending on who views them.
