This video and discussion has come up before in the past. The very first shot in
the video clearly demonstrates that both throw and spin transfer are occurring. The right side side throws the OB to the left and imparts left (clockwise) sidespin to the OB. That's why the stripe of the OB does not remain vertical, as it would with no spin transfer. The OB stripe wobbles because sidespin is imparted to the ball.
As others have pointed out, you cannot get throw without spin transfer. They come hand in hand because they are caused by the same friction force between the balls. Diagram 1 in the following article illustrates what is going on: "
Throw - Part VIII: spin transfer" (BD, March, 2007). And the following super-slow-motion video clearly shows the effect:
HSV A.66 - Straight-on shot with english and slow speed.
The only time there is no throw or spin transfer is with "gearing" outside english (or with a straight stop shot with no sidespin). The following video explains and demonstrates this effect:
HSV B.33 - Outside english gearing, and cut and spin-induced throw. And more information can be found on the
outside english resource page.
For people who want more convincing concerning spin transfer (from either a cut angle or spin), the following resource page contains numerous videos, instructional articles, illustrations, and examples showing very clear evidence for spin transfer:

There are certain types of shots that are not possible without spin transfer. Here are some examples:
NV B.20 - Spin transfer bank shots
NV B.22 - Two-times and three-times across bank shots
And more can be found on the
spin transfer resource page.
