[2019] Man, can’t believe I got outplayed like this. Time to upgrade my gaming chair

Seems like you had a severe latency spike for a brief moment (it even looks like you got disconnected). If your client can't be synced with the server for that duration, it won't know the position of the player and will just extrapolate then try to catch-up as soon as it's synced again which will look exactly like what is happening in your video.
