Los eventos generados por el mono de Android no son los mismos cuando la semilla es la misma

Yo uso el mono para poner a prueba mi aplicación. En https://developer.android.com/studio/test/monkey.html He leído:

-s <seed> Seed value for pseudo-random number generator. If you re-run the Monkey with the same seed value, it will generate the same sequence of events.

Pero cuando corrí el Mono dos veces con la misma semilla y luego comparé las salidas, las coordenadas de mis eventos ACTION_UP y ACTION_DOWN no eran iguales.

Salida # 1

¿Por qué? Yo esperaba ver los mismos eventos y, por lo tanto, los productos idénticos
