It appears the Bypass Protection requires you to "prove you are the owner of the phone before the factory data reset...log in with your Google account that was added to the phone before resetting." What you are expected to do is REMOVE all Google accounts BEFORE resetting and this would not have happened. The purpose is to (attempt to), prevent the phone from being stolen and then set up with another user, (hopefully), making your phone less prone to theft as it should thwart thieves and make the phone unmarketable. However like almost every way to prevent access to a phone, there are methods eventually discovered to circumvent such protection.
There are ways to get past this 72 hour lockout, but it requires some careful navigation of steps and utilization of Samsung's website and a tool that needs to be downloaded and sideloaded on the phone, after installing the partner app on a desktop PC and connecting it to the PC with a USB cable.

Here's the same video provider with your model phone, it may be easier to follow with this link but either will work.
What is happening is that the combination of the sidesync app on the desktop and phone, and the Samsung account you create allows the phone to be FULLY factory reset, erasing ALL DATA, including the previous google account information. This way it will act like a phone right off the retail shelf upon restart.
