Quote from LASORS, E1.5 - IR(A) Re-validation and Renewal: Important Note
SPA IR privileges are not type or class specific -
the holder of more than one SPA type or class
rating is required to re-validate the IR on only one
SPA type or class (usually the most complex
one). However, the holder of a ME IR must
revalidate on a ME class or type. An IR SPA ME
will confer SPA SE IR privileges whereas an IR
SPA SE does not confer SPA ME IR privileges.
(Emphasis added by me.)
Seems like your instructor friend is wrong.
