The holes aren't really holes but are actually bays at the top and bottom of the image. What you'll have to do to fill those is to draw a line at the top and bottom of the image and call imfill, then erase the lines afterwards.
binaryImage(1,:) = true;
binaryImage(end,:) = true;
binaryImage = imfill(binaryImage, 'holes');
binaryImage(1,:) = false;
binaryImage(end,:) = false;
