For those’s that want the link to the drill video, it’s here:
Having just listened (1:08) she is speaking it accurately to my ear. I can see why you might think that the second noise sounds like a 4th tone, but this is because she is going from a very high pitch, all the way down to the lowest pitch in a short amount of time.
Had she been speaking it with a 2nd / 4th tone pattern, there would be a lot more emphasis on the 4th tone, which would first rise up, and then drop down, rather than drop down.
I have made two audio comparisons for you to listen to. For a native speaker, the difference is clear, but for many learners, it’s a but more subtle.
Check out the playlist I made and see if you can tell:
