I grant you, the system can seem a bit lively in gusty conditions, which alarms some pilots.
Initially the thrust does not need to increase to follow the speed target because the gust itself has caused the aircraft to follow the speed target. Whether the thrust comes up subsequently depends on how transient the gusts are. The gustier conditions would tend to result in less auto thrust activity while descending through different strengths of relatively steady wind will result in the speed target remaining elevated for prolonged periods and the thrust will need to adjust to maintain it. There’s also the fact that GS mini has been nerfed somewhat in the NEO aircraft so the system is less “active” in those.
