If you have ever watched a launch of one of the SpaceX rockets on television, for instance, you will notice that at various times during the launch, part of the picture will perhaps focus on a part of the rocket that is entering into orbit. At the same time another part of the picture will focus on the main booster returning to earth and landing again on the launch pad. It is all one and the same event, taking place at the same time but focusing from different viewpoints. The events of Revelation are similar to this.
