Yes, it does fade but not completely, a small trace is left behind. See the photos below.
This is a screen capture from your example:
On my monitor the trace is faint but clearly visible.
Here I manipulated the brightness and contrast in Photoshop to enhance it. If the trail was 0% opaque in the first place, it shouldn't be visible at all, even with the brightness and contrast added, right?
