If the `^{tree}` does calculate a commit internal sourcetree hash without other commits, then yes.
If it does rely on other commits and accumulates the sourcetree over the chain of commits, then it does not calculate the hash by the difference and can not be applied as I have described.

Nice, but I can not apply this over a git hub or a web interface without a clone.
