Not Correct IMO.  The final centering of the steering wheel is a very minor
correction of static friction induced errors and inaccuracies in centering
the wheel during the static toe adjustment.  Picture if you will, a
perfectly aligned DIY job having only an off center steering wheel.  We now
pour concrete around the wheels so nothing is free to move between wheels
and ground, and relative alignment to the chassis is fixed.  We can now
adjust the position of the rack within the linkage connecting the two strut
steering arms without changing the effective linkage itself.  Thus, we
center the steering wheel and the alignment remains unchanged.

Now, try to get the damned thing out of the concrete!  (The humor you asked
for.)
