What constitutes an insignificant interruption between pronouncing Tasmiyah and the actual slaughter?

Primary text

If a person lays down a sheep for slaughter and pronounces the Tasmiyah, but then pauses—such as dropping the knife, taking another sheep, returning a greeting, asking for water, or similar brief acts—and then proceeds with the slaughter, the meat is lawful. This is because the Tasmiyah was made for that specific sheep, and the separation was only a minor interval, which is treated as if no interruption occurred.
