```Yes, Mathematica orders the plot iterator limits so they always go from
minimum to maximum.

If one wants the axis directions reversed, it can be done in the following
way using the CustomTicks function from DrawGraphics.

Needs["DrawGraphics`DrawingMaster`"]

x y^2 /. {x -> 5 - u, y -> 8 - v};
Plot3D[%, {u, 1, 4}, {v, 0, 8},
Ticks -> {CustomTicks[5 - # &, {4, 1, -1, 5}],
CustomTicks[8 - # &, {8, 0, -2, 5}], Automatic},
AxesLabel -> {x, y, z}];

One of my students just noticed that the plots generated from

Plot3D[x y^2, {x, 4, 1}, {y, 8, 0}]
and
Plot3D[x y^2, {x, 1, 4}, {y, 0, 8}]

are identical.  In general, how does Plot3D handle the iterators that
define the plotting domain?
