You are correct sir!
A meter is an arbitrary unit in world-space coordinates. It helps keep everything in scale. Thus a human is 2 meters tall, etc..
In general most terrain engines I've seen go to the meter resolution on the terrain vertexes and the sub-meter resolution for the color texture texels.
If there is a heightmap involved, it is almost always the highest resolution of the engine. New engines are now adding procedural detail between heightfield samples.
