Determining latitude has been possible with a high degree of accuracy for centuries. Longitude is different. It required very accurate clocks. Until the development of the ship's chronometer longitude determination was largely guesswork. So I suspect some of the phantom islands were already identified, and the 'new discoverer' was just in error by several degrees of longitude.
