Sorry if I’m misunderstanding your comment, but your point is essentially correct: the puzzle can be solved using only the per‑coordinate feedback.

Since you mentioned “green,” I’m assuming you’re referring to Euclidle’s Absolute hint type. In that mode, each coordinate can indeed be narrowed down efficiently using a 1/2‑style strategy.

However, when the hint type is not Absolute — what I call Relative, where only directional information is provided — the situation is different. Because the feedback is purely relative rather than per‑coordinate, the simple 1/2 strategy does not directly apply.
