As long as the input shaft is turning, there is lubrication provided.  When flat towing only the output shaft is turning, so no lubrication.  

The input will be turning at idle. The output will be turning at whatever road speed is.  I would not trust the lubrication splash is enough for highway speed. Won’t be long enough for it matter for a stop light, but down a mountain?
