Sorry, I'm too lazy at the moment to go and read the ImageMagick source, but in the light of Joris' recent comments, I wonder how you handle that reliably, if it's really pure TIFF concatenation. I mean, there's nothing in a TIFF that tells you the size of the file, so the only way would be to either scan for the TIFF signature (dangerous), or to determine the "last" offset that isn't referred to anywhere (complicated, and with the image deletion problem Joris sketched).

ImageMagick's MIFF has nothing to do with TIFF. MIFF is a rather simple format in which a sequence is comprised of the same stuff which forms a stand-alone image, but concatenated together.
