"Ultimate life form" does not have a true definition in Sonic lore; yes Shadow was created for the purposes of achieving immortality, yes Shadow is referred to as the "ultimate life form," but it has never been stated that an ultimate life form is an immortal being.

It is not clear what Shadow meant when he said Sonic might be the ultimate life form (Shadow says "might" not "must" as the video claims), maybe Shadow said it as a mark of respect (Shadow prides himself on being the ultimate life form, so to use that title on someone else is to let go of his pride), some may point out that Sonic was depicted in an echidnian prophecy and therefore may be some sort of transcendent being or demigod, some even think Shadow was based on this prophecy and that Gerald was essentially trying to create Sonic when he worked on Project Shadow.

But the important thing to remember is that all of the above is speculation, without official confirmation we will never know what Shadow meant when he called Sonic the ultimate life form, so to claim it as evidence that Sonic is immortal is just speculation.
