The challenge there was combining code systems. 4K as a standard had been used for a relatively long time in digital cinema and editing, and I believe the long-dimension standard was chosen based on telecine processes for scanning film for digital editing and effects. Consumer tech wasn't anywhere near those sorts of resolutions for a very long time, and the 480/720/1080 definition was based on TV broadcasts displayed with CRT scanlines. Then consumer display density rose to the point that it became relevant, and 4K was the preexisting professional name for digital displays in that resolution. It's complicated, but I don't think the choice was intended to confuse.
