I don't think it means Einstein was wrong or that one galaxy is moving "faster than the speed of light". It means in respect to each other two galaxies are moving faster than the speed of light. In other words each of two galaxies is going faster than half the speed of light, one of them being us (in relation to the other observed Galaxy).
