Some shortpass filters only block 700 nm to 1100 nm and are not rated for performance above 1100 nm, since the silicon sensor cannot "see" light above 1000 nm anyway (but may be damaged by sufficiently strong amounts of it). So, perhaps Sony was using an IR block filter that blocks near IR from 700 nm to 1000 nm but doesn't block 1550 nm perfectly.
