No it was not. No idea why he drives that GPS connection to UTC. It seems totally unnecessary for video processing. It only has to be synchronized between each other to work perfectly synchronized to each other, not to Global Time Sources.
The PTP is only protocol which ensures that clocks of all connected devices are synchronized to one called Grand Master Clock. It could be done using PPS and coaxial cables. It is just convenient as it adjusts automatically for cable length. It is not necessary or revolutionary.
This was a great talk by Thomas. Thank you for making it available.

Why that has to be synchronized to GPS? Is it not enough to keep good quality oscillator?
