But the components of the vector joining two events, or their projections on to the time axis or a space axis are not at all expected to be equal.
Maybe it is even possible that if one event precedes another in one reference frame, in another reference frame the other precedes the one.

In other words, the order of occurrence of events may be different in two frames. This indeed can be the case, and Minkowski diagrams can help us to see why and in what circumstances.
