0:32 - says "Missing 2.45", but the inspection for the 2.45 is actually being filmed. The solving was not filmed, somehow.
0:40 - you can see a scene transition, and the orientation of the 3x3 on the table also changes. This is where the inspection for the 4th solve actually starts.
0:48 - starts solving
So while it seemed he took more than 15s, that was the combined inspection of the 3rd and 4th solves.
The reason the 2.45 was missing is because my phone ran out of space to record.
