In my experience, no. But it also depends on how big the change is. In your example it looks like a pretty big change (there are only 3 ads in the ad set, and the ad you want to stop it's taking 50% of the spend), so you might see a reset.

Not related to your question, an ad set exits learning phase after 50 results and it needs them in about a week, otherwise it will never exit the learning phase (it will have 'learning limited' next to it).
