Yes, but these islands are a lot further from the land on either side of the ocean. When you look at the map it looks less impressive than Alcock and Brown.

But in fact this 432 MHz contact is over a greater distance, 3867 km, than Alcock and Brown's flight of 3040 km (https://en.wikipedia.org/wiki/Transatlantic_flight_of_Alcock...)

So calling it trans-Atlantic actually undersells it in comparison with other well known trans-Atlantic feats while at the same time setting people up to think the opposite.
