Mark,

You should create a new branch for any independent change.
If you don't do that, all your changes will appear to depend on the  
others.

If your two changes are made to fix the same issue, for example to  
take in account the reviews on the first change, then you shouldn't  
submit a second change but rather modify the first one by using

   git commit --amend

You can still merge your two changes with

   git rebase -i

resubmit the merged change to gerrit and abandon the second change.
