So he thinks it is mostly be about aero. Maybe I'm in good company.

It makes me think it's more about aero. The RB16 had a flat top arm, and a slightly inclined lower arm (the arms diverged rearward instead of converge as on the RB18/19), which provides the opposite sort of caster change that the RB18/19 would provide. This might be a change in chassis/suspension philosophy, or simply an indication that suspension design plays second fiddle to aero.

That explanation is completely wrong.
The diffuser has a complex curvature, after the kick there is a concave surface where there is some pressure recovery due to a drop in expansion. At the edge and under the beam wing, there is a specific flick on the floor, introducing another area of low pressure, which especially works together with beam wing to further drive the whole floor by generating big suction zone. When you have a big suction zone here, the whole mass of air under the floor also speeds up to reach this low pressure zone. However, these two points (underfloor kicks and diffuser design) are not the only secret.
They used the word "subtle" with regards to a change in suspension wishbone shroud (presumably the one with the driveshaft in it), so probably not going to be caught by a relatively long range shot from that angle.
