Assuming you have a product/release branch and many others, then I'm guessing the author means you should merge product into your own branch and deploy that, before merging your branch back into product (and deploying it). That should work fine with multiple branches in most cases, so long as you have a system to stop anyone else deploying their branch while yours is running.
