When testing multiple subjects, only runs the last one

[Gustrucco]

For example, in this exercise, this solution passed the tests:

procedure DibujarLineaRoja3() 
{
  Mover(Norte)
  repeat(2)
  {
    Poner(Rojo)
    Mover(Este)
  }
  Poner(Rojo)
  VolverAtras()
}

The solution that shows Gus passes but that's not correct because this is the solution that should pass:

procedure DibujarLineaRoja3(){
  repeat(2){
    Poner(Rojo)
    Mover(Este)
  }
  Poner(Rojo)
  VolverAtras()  
}

procedure DibujarLineaAzul3(){
  repeat(2){
    Poner(Azul)
    Mover(Este)
  }
  Poner(Azul)
  VolverAtras()  
}

In fact, this solution also pass and it's incorrect because of the Mover(Norte) of the last code line:

procedure DibujarLineaRoja3(){
  repeat(2){
    Poner(Rojo)
    Mover(Este)
  }
  Poner(Rojo)
  VolverAtras()  
}

procedure DibujarLineaAzul3(){
  repeat(2){
    Poner(Azul)
    Mover(Este)
  }
  Poner(Azul)
  VolverAtras()  
  Mover(Norte)
}
