What you're saying is that two things can be separately defined by also taking into account their time coordinate. This is true: don't think of time as some separate thing to distance, think of it as a *kind of distance*. So you can hop on the spot in London, and hop on the spot in New York, but you can differentiate the two acts (even if you were doing the exact same thing), by looking at their spatial coordinates (i.e. where on the planet/in the universe you were). The same is true for time... Time is just another coordinate.
Einstein/Lorentz also showed that if you see someone do two things at the exact same time (simultaneously), to another passer-by the two things may be seen to occur at different times (i.e. not simultaneously).
