You're right.  I missed that definition.

The problem is, "its contribution" isn't defined, "contribution" is.
"Contribution" would be seem to mean what Mozilla Public License calls
"contributor version", which is the program up to and including the
contributor's modification.

It's not clear whether "its contribution" should mean this, or just the
modifications made by the contributor.

The most reasonable (and conservative) interpretation is probably that
"its contribution" only means only the modifications made by the
contributor, though this is narrower than MPL, Apache 2.0, GPLv3, etc.
