In theory yes but in reality Earth rotates and orbits the Sun. Any particular observer outside our solar system has a very low probability of catching any one of those beams at the moment it's photons are reaching them. There's also little chance of those beams will ever hit the same observer. The inverse square law also means that a potential observer would need to be in a relatively small radius from our system.
