# pgfplot z projection shows up at wrong place

Starting from the example http://pgfplots.net/tikz/examples/contour-and-surface/, I would like to make projection of a surface, defined by a table. The X and Y projections work OK, but the Z projection appears at the top, rather than at the bottom. I guess it is because of the log scale. What do I wrong? The picture below illustrates my problem. (I know, the picture is not attractive and not reasonable, but I wanted to reduce the size for an MWE)
