When reading "one of whom is moving at close to the speed of light compared to the other" in the explanation I'm reminded of the (non-)joke "What's the difference between a duck? One of its legs is not the same." Because of frames of reference ''both'' of them are moving at close to the speed of light compared with the respective other. Which doesn't affect the disagreement about the simultaneity of observed events, of course. That still potentially/inevitably happens.

You don't have to move close to the speed of light to create this effect, you just need to go close to the speed of light to make a noticeable difference. | You don't have to move close to the speed of light to create this effect, you just need to go close to the speed of light to make a noticeable difference. |
