Would this void Rolex warranty?

[GMTSpas]

I purchased a pre owned Rolex watch from a forum member that was signed and dated by AD. The original name was blacked out and another name was written right above it.

I’ve check a few forums and people have mentioned the card follows the watch not the name, however does anyone know if the altered card voids warranty? I’m sure it is not a big deal. But I have never seen it before.
