No it wasn't. Your "10 seconds" consisted of two short "blips" - one to the full ND position for about 1s, then back to neutral, followed by a "blip" to the half-forward position for less than a second, then back to neutral before resuming the NU input.
Notice the neutral position of sidestick. The NU stop is close to vertical
The NU travel is much shorter than max roll command.
Having used one in the simulator, I can tell you that's not true. You're using a video in which the lens is distorting the apparent Z-axis.
This was not accidental - this was a pilot making a "haché" of controlling the aircraft when he didn't (immediately) need to.
