Rules of JAR OPS3 or OGP recommendations or company-specific currency rules are yet another story here.
JAR-OPS recency requirements are stated in 3.970, it also waives the night circuits if you have an instrument rating.
JAR–FCL 2.026 is explicitly not applicable for JAR OPS 3 operations, as the title says: "Recent experience for pilots not operating in accordance with JAR-OPS 3"
JAR-FCL 1.026 requires only one night landing for fixed wing, so this is indeed a difference.
