Cell count issue (sometimes)

I have a user that has reported a strange (to me) issue that I cannot explain and hope to get some answers.

When previewing the Classification properties of a raster (from a FGDB) that is loaded into ArcMap 10.1, the count is double what the row count * column count.  For example,

Cols & Rows: 1467, 1354 = 1986318 cells

However, if we preview the symbology properties, Classified renderer (clicking the "Classify" button) it shows in the classification statistics pane:

Count: 3972636

This count is double the cell count of cols * rows above.  This only occurs on some rasters (there are other rasters that show the same count per the above example).

Am I misunderstanding something simple here?

Thanks for any input,
