Morphology
Both constituents contribute directly to the meaning: 'instinctive' (driven by instinct) modifies 'reflex' (an automatic response), so the phrase simply denotes an automatic response driven by instinct. This adjective+noun composition is predictable and cross-linguistically common, so a B1 learner who knows both words will readily infer the MWE meaning.
Etymology
Instinctive reflex comes from simple images like a baby closing its hand around a finger or a knee that jerks when tapped; both are fast, natural movements. That's why an instinctive reflex, with instinctive as a natural urge and reflex as a quick movement, means a movement that happens 'without thinking' — a natural, automatic response.
