That is correct. If you look at the exif info, you read:

Filename - 6.jpg
...
ImageWidth - 3264
ImageLength - 2448
...
ExifImageWidth - 3264
ExifImageHeight - 2448
...
Orientation - Right top

What you see is the result of "smart" image viewers, which read the exif 
info and read that you held the camera sideways and there fore rotate 
the image.
the image istself is still 3264x2448
