I agree that had the car simply swapped ends, even after backing off the
throttle, with the brake handle hauled tight at speed, the leading shoes
would be on the wrong side of the drums to be effective - most of us have
re-positioned reversed shoe sets over the years to "magically" restore
braking power...
With the throttle lifted, in neutral and/or clutch engaged, I would think
that the CoF between salt and tires is low enough to lock them up until it
swaps ends back to nose first, reloading the shoes hard against the drums
(providing the lever is hauled tight). Theres a good chance that a hard tug on
the brakes would induce a Hollywood spin regardless of which end is pointing
wherever...
I'd also speculate that once the wheels were locked up, with all excess slack
out of the cable, when the tail points in the direction of forward travel
again, the force holding the shoes locked will outweigh the negative torque
against the shoe set. In the last few frames right after the timing tower
pass, the car swapped ends one last time right after the tires squeal (for the
first time) and it looks like the brakes were set.
