Isn't it gnuplot who does not read it properly?
I have tried
 	set view map; splot 'a.dat' with pm3d
and
 	plot 'a.dat' with image
with

0	0	0
0	1	-1
0	2	-4
0	3	-9

1	0	1
1	1	0
1	2	-3
1	3	-8

2	0	4
2	1	3
2	2	0
2	3	-5

3	0	9
3	1	8
3	2	NaN
3	3	9

and it was the pm3d style which skipped the point, not the image style -- thus 
the opposite observation.
