SDO_SAM.TILED_BINS using xdivs and ydivs fails

Question

I'm using SDO_SAM.TILED_BINS to generate some grids, but with some combinations of xdivs and ydivs if doesn't return correct.
To be simple, theres a example like the one in documentation:
If xdivs=7 and ydivs=7
SELECT * FROM TABLE(sdo_sam.tiled_bins(-180, 180, -90, 90, null, null, 7, 7)) ORDER BY id;
it is OK, it returns (7+1)*(7+1) rows, from ID 0 to 63.
If xdivs=5 and ydivs=7
SELECT * FROM TABLE(sdo_sam.tiled_bins(-180, 180, -90, 90, null, null, 5, 7)) ORDER BY id;
it is OK, it returns (5+1)*(7+1) rows, but some IDs repeats and the grid is not complete.
I'm returning SRID as null, it doesn't matters to me, but if I use one, the same problem occurs.
Tested in Oracle 10.2.0.1 and 11.1.0.7.0
Maybe I missing something?
Thanks in advance

Rob,
You can use SDO_GEOM.SDO_MIN_MBR_ORDINATE and SDO_GEOM.SDO_MAX_MBR_ORDINATE to compute the length and width of an mbr.
