It's an impossible stretch and also a bad idea. Insisting on that interpretation opens up other issues. Revision history may not be available in some cases for various reasons, such as if one pays someone for a large contribution. We could get into arguments about how granular commits need to be to comply with publication requirements. Digital achives containing source code files are certainly customary and easy to use, as opposed to reams of printouts. It would be just as customary and modern to publish on CD and mail the stuff out to anyone who demands the code. Continuous or timely delivery is not guaranteed by the license. One week of wait time is actually reasonable for a process like this, though I expect it might gradually get worse in line with their long-term objective of making the entire thing painful for outside developers.
