Considering that H-9a and its coupling partners (H-9b, H-8a, H-8b, and H-14) can indeed be classified as forming a near(!) first-order spin system and keeping in mind that the majority of organic molecules contain structural motifs that form non-first order/higher order spin systems, the observed mismatch between visual and proper QM-based spectral interpretation occurs in a wide range of molecules and deserves much wider attention in HNMR spectroscopic data interpretation.
