RE: solve({ 2*x^2*y^2 = 0,2*y^2*x^2 = 0},{x,y}) [Enter] -> { [x,0] [0, y] }
The reason is the same as for solve(x*y,[x,y]) or solve(x*y,x), no special case for y=0. If your system has more unknowns than equation (after gbasis computation), it is solved with respect to the last unknown(s) it depends on, regarding the first "unknown(s)" as parameters, and solve happens in the generic situation.
