If they really did mean pairs, then they may be referring to the fact that when cranking the engine for startup, a pair of coils fire simultaneously until the PCM determines cylinder ID and knows which cylinder of the pairs is on the power stroke. This will occur for the first 6 revolutions of the engine at startup, or if there is a failure of the CranKshaft Position (CKP) sensor.
