I'm not sure what problem you're fixing from this description?

It's takenme a few minutes to work out that:

"If SCRATCH_DEV_EMPTY_SPACE + 50GB is larger than the filesystem
size being tested, then the configuration being tested is invalid
and should fail. Currently we only check that
SCRATCH_DEV_EMPTY_SPACE is greater than the the filesystem size. Fix
it to check the combined empty space fits in the filesystem being
tested."

Otherwise the change looks good.
