Simply because if a trailer is being prepared, they can just record the lines for that trailer first of all, then proceed to the bulk of the VO work for the actual game. Not that I'm predicting or expecting a trailer or even anything at all at E3, at this point.
Don't get me wrong, the same thought has crossed my mind about just doing trailer lines.
It's pretty unorthodox though, and might not result in the best performance from the actor/most appropriate for the scene. Not to say it hasn't happened before in high profile games; MGS4's E3 2016 voice acting was recorded specifically for the trailer but I think all of it was later re-recorded (maybe with the exception of the "war has changed" monologue) and had some changes in line delivery too.
It could happen, but there are caveats like if they're willing to spend money recording lines they may have to go back to later, and just the simple time factor of getting the lines implemented and facial animation into a presentable state. If it were to happen, it'd probably have to be with the Japanese cast just to make the process as quick as possible.
