Does SHA-7 belong to the US NSA?

As everybody knows, the SHA-n is a series of cryptographic algorithm developed by the NSA and published by the US NIST. The current SHA-n lineup includes SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512.

On the contrary, SHA-7 (see this link – italian only, sorry), a “proprietary, patented encryption algorythm” developed by an Italian company doesn’t belong to the original “family”. And doesn’t have any endorsement by the scientific community.

I wonder why SHA-7 designers have choses this confusing name for their code.
