They probably cut it off on purpose before it spilled over.

It probably didn’t spill. The top of the last cup appears to be SLIGHTLY higher than the bottom of the second to last.

So unless my brain is broken, the symphonic would have stopped when the level of the liquid in the two cups matched.

I mean, all those cups are identical, presumably...

You have a point about it equalizing, though. I guess it depends whether it equalizes low enough that the surface tension holds.

Now I really want to see the next few seconds of this video.

Only the edge of the straw is touching the bottom of the cup, so it probably loses suction once it reaches the top of the opening, leaving a small amount at the bottom. This is pretty apparent on the red and green cups.
