No.  There's no promise of the range reversal affecting sampling order. 
  It affects the relation between coordinates and positions on a graph, 
not the order in which those positions are visited.  That ordering is 
generally unimportant, since you couldn't spot the difference in the 
resulting image anyway.

The table driver makes that a bit mor complicated, of course.  But, like 
with so many problems, parametric mode helps:

gnuplot> set table ; set parametric ; set samples 15
gnuplot> f_x(t) = 10 - t
gnuplot> plot [0:10] f_x(t), f_x(t)**2
