"wtf's the point?"

Well there's great divergence of opinion on the subject of whether dispersion (radiation pattern) matters. I'm among those who thinks it does. Here the f's the point as I see it: More natural timbre.

Most of the sound that reaches your ears is reflected sound. While your ears derive spatial cues primarily from the direct sound, the reflected sound plays a very significant role in perceived timbre. Note that live instruments generate natural-sounding reverberant fields, but few loudspeakers do (mentally compare listening to a live piano from the next room versus listening to a pair of speakers from the next room).

In my opinion the closer the speakers come to getting the reverberant field right (assuming all else is equal), the more natural and long-term relaxing they are going to sound - and you can't get the reverberant field right without paying a lot of attention to dispersion.
