This looks to me like a bug. The final resolution on Issue 4.6 

states clearly that sameAs is a synonym for sameIndividualAs and says 
nothing about it only being in Full. The minutes of the relevant telecon 
(Nov 11) contain a suggested methodological guideline that sameAs may 
typically be used in Full when the types of the subject/object are 
unknown, but that's something different.

Not true, see above.

The introduction of the synonym was part of a WG compromise (some 
preferred sameAs instead of sameIndividualAs). I see no reason to 
revisit this decision.

I propose the S&AS, Guide and Ref editors take actions to ensure their 
documents are consistent with the current resolution.
