kt88 tube placement

The specs of the Genalex kt88 says that a kt88 can be mounted horizontal but you have to take care that pin 4 and pin 8 are in a vertical plane. What does this mean?

English is not my first language. Does it mean in a vertical line, so pin 4 is pointing down and pin 8 up in a vertical line?

So the getter on top will be hotter then the other getter facing down.
