Motivation and Context / Related issue
This PR closes issue [#418] by adding a note to examples/dcgan.py that the DC-GAN example now uses a single combined backward pass to avoid double-charging the privacy budget. This makes it clear to users and maintainers that the double‐charge bug has been addressed.

Noob question, it seems PR(https://github.com/pytorch/opacus/pull/494) is on the fly, which means the problem has not been solved yet?
@HuanyuZhang, PR #494 mentions PR #474 as solving the same issue with the privacy budget, so it seems the issue is indeed solved?
