Assuming 10 is more like branch_10...because "Tag names must start with an 
uppercase or lowercase letter..."[4], and a branch is a special tag[5].

should not the above be:
cvs -f update -j 10 -kk file1
???? to join[6] the information???

I am not sure that it makes CVS sense to run this command until you have 
committed the merged file to the repo. which version should CVS be pulling 
info from? Do you care which revision the info comes from? Do you care that 
the info is by definition wrong(does not apply to the version of the file in 
your sandbox)?  <sarcasm> Don't you love the Tail chasing that can be done 
when you make the mistake of trying to use RCS keywords? </sarcasm>

Is -kk sticky?  i.e. run `cvs status file` and look for something other than 
(none) after Sticky Tag.
If you put a different keyword, such as $Id$ in the file does your method make 
it expand?
Do you get different results if you use[2] -kkvl instead of -kkv, because 
$Header$[3] states locker (if locked), and -kkvl provides locker name?

Speculation and hand waving: CVS knows the file was modified from what it sees 
as it's default version, CVS knows the data it has for the header would be 
erroneous, because this version of the file has not been committed, so it does 
not apply it.
