It depends how the technical fault slate is put to air.Back in the days where automation was controlling tape machines there would often be a 5 second delay between pressing take next and it cutting to a programme, as the source would have been programmed to take account of the 5 second pre-roll of the VT machine
What you see in that video is the playout automation system (Morpheus) taking a few seconds to react to the "take next" command. This is fairly standard. In the playout suite I look after it takes around 2 second, and here it seems very similar. This "pre-roll" delay is very intentional, it gives the automation time to send the commands the relevant devices (in this video an ICE server) and sync up the main and backup copies of the channel so that they both cut in sync with one another.
