I think it's not based on any kind of agenda. The block is short, only airs once a week, and only airs a specific kind of show, so my opinion is that a show gets to be on Toonami whenever the circumstances allow it. I mean.... think of how long it took for Toonami to air Toyko Ghoul. And I bet in time, we'll have more VIZ shows than Funimations shows.
