In fact, I have no idea what the geometry of the airport is like when it comes to connections, I'm always just sprinting and following signs for the E gates, because that sign takes precedence to me, so I have no idea about the escalator. For the kiosks at points #2 and #3 I also glossed over because all international arrivals (connecting or entering) must present their passport to CBSA. I glossed over the kiosks because sometimes they're not functional/the room is empty, and you're beckoned by an officer to clear with them rather than waste time at a machine. Sometimes there are neither machines nor border services officers, and there's just a red box where you self declare. I've seen this "red box" when connecting onward to international flights during peak holiday periods.

This paragraph I've written just exists to say why I said both pages were functionally similar. the primary steps (1,2,3,4 above) will guide your way through the airport, but there will be staff along the way at each phase to direct your literal footsteps where you need to go. Understanding the typical connections steps is good and I'm glad you found a video (I'm not sure which one but you mentioned E so it's a Terminal 1 video), but be aware that sometimes there are closures which could affect where you go in the airport. Namely, the closure or irregular operations of the connections facility would impact you the most, but there will be help to guide you along anyway. Just know the primary steps!
