A referee can and should be able to stop play to issues a TW or TF. If a player hits a ball causing it to pop up for an easy overhead winner and the just throw there paddle towards the net, that would be an instance where a referee could stop play and issue the TW/TF. This could be looked at as the referee stopping play for a distraction also and then issuing the TW/TF. There are circumstances where stopping play and issuing a TW/TF do occur though, so I feel that taking that wording out would bring up more confusion.
