If the stuff you were rolling out was bad/broken then you _may_ not want any 
of the other developers to build on that source.  By committing the current 
(sandbox you ran  `cvs update -jDEV_1_32 -jDEV_1_31` in) sandbox you put the 
"corrected" code back on the HEAD so that when others do normal updates they 
get the change you made.

cvs update -jDEV_1_32 -jDEV_1_31
undoes the changes that occurred _between_ DEV_1_31 and DEV_1_32.

This would undo the changes that occurred between DEV_1_31 and DEV_1_33.
Assuming that DEV_1_32 was tagged onto the repo between DEV_1_31 and DEV_1_33, 
then yes it would role out the changes in DEV_1_32 too.

But I think that means `cvs update -jDEV_1_32 -jDEV_1_31` might remove all the 
files that were not changed between DEV_1_31 and DEV_1_32.

For what you are doing I believe that would be a bad idea. see:
http://lists.gnu.org/archive/html/info-cvs/2004-12/msg00209.html

I have a script (owned by the DoD) which I describe here
http://lists.gnu.org/archive/html/info-cvs/2005-02/msg00367.html
to build (tag names) and apply all my tags.

Yes,
cvs tag -r1.2 Tag_C file
