When you enter a station, a few values don't get reset to default values.
Velocity
and
isGrounded
is some of them that is stuck in the state they were in before you entered the station. Which we also have no control over.

Could also be that this is intended, but filling a bug report so that a clear answer can be given, and possibly fixed/updated documentation to include this.
Repo example;
  • Stand by a station
  • Jump
  • Enter station mid jump
  • Look at the avatar debug menu
  • See
    isGrounded
    is False, while you're in the station.
  • Exit station
  • isGrounded
    is now True
It's the same for Velocity
