It's possible the author is unaware that there are cables that have a USB-C (TB4) connector on one end and a DisplayPort connector on the other. This should directly support running DisplayPort 1.4 off just the dock they purchased without additional dongles. (Which would also work with the OWC TB4 dock you mention).
Possibly they had a specific need for actual DisplayPort ports on the dock though, and because they specifically wanted DisplayPort 1.4, that ruled out TB3 docks.
How do you like that OWC dock? It looks pretty nice. I also noticed that CalDigit has successor to your TS3 that looks pretty nice too.
