The default eyes in121 work fine in DS, the 122 eyes no longer work with the "point at" function. I don't have time to try the BBeyes right now, but my assumption is the same as yours, that the point at function in DS likely works the same as in Poser.

I just tried it in Poser as well, and the same issue, 121 default eyes "point at" fine, 122 do not.
