I believe that an ATP (such as FO, who was acting as PIC in this
instance) can give instruction in air carrier operations - and
therefore, the FO could sign his log book as dual received.

IIRC, the ATP must be rated in the -757 to be able to sign off instruction.
The -182 wouldn't need a sign-off if he is MEL rated. Logging SIC time is
not the same as acting as SIC.
