I have had pain with not all views supporting multipage TIFFs. What you
describe is implemented in this way inside the file:

[TIFF header]
["Directory" of information for first page, including offset to next
directory]
[...Image data...]

["Directory" for second page]
[...Image data...]

...etc...

A lot of viewers only bother to look at the first directory and stop
there. You therefore cannot rely on multipage TIFFs working for everyone.
Most of the large imaging systems I have seen therefore avoid multipage
TIFFs.
