Anything that risks producing incorrect test results, I suppose. I find it
practical to use the existing tree for diagnosing errors and trying patches.
I'm not a Boost developer so I don't typically have a source tree other than
for regression testing.

The suggested command doesn't use the network at all. Git caches the whole
repository in a hidden .git subfolder so it just replaces whatever needs
replacing from there. It takes 15 and 50 seconds to run respectively on two
machines I have.

After further testing I would suggest adding --quiet to remove some
unnecessary output as well as removing the unnecessary parentheses:
git submodule foreach "git reset --quiet --hard; git clean -fxd"
