The game definitely is inconsistent, and gets more and more so over time. But if he switched the game's perspective, that would be a whole new level of change, and a poor choice to make this far into the game. I was an English major and dabbled in writing, so suddenly changing the point-of-view for the story would throw me. But then again, it's not really a story or a game at this point. It's a collection of above-average renders loosely connected by way below-average dialogue and writing.
All I'm getting at here is that you and I and most everyone else has injected much more story into this game than is actually there. The main purpose of our brain is to take the bits and pieces we see and try to make sense of it. And that sense/perception is going to be different for each brain that operates on it. The dialogue is so vague, non-descript, and the images just so generic and in some cases don't even reflect the mood of the dialogue that our imaginations are forced to work overtime to make sense of it all.
The story and dialogue in this game seems to only serve whatever scene he has decided to render next and has little to nothing to do with what story he has already told and scenes he rendered before. The fact that the BDSM scene is the mechanism he is using to make Mom want to have an orgasm from Max is typical for him. When he can't come up with a way to get the Incest event to happen because of his mental block, he runs to BDSM to solve it. All of the women in this game are submissive (yes even Alice who has recently gone off character and become a DOM only because it serves Lisa's Submissive sexual tendencies). Kira and the non family members are the only non subs in the game.
That's because he can't imagine incest happening in any way other than Rape, Force and coercion.
As for how the Movie shoot will be seen there are a variety of ways for us to see it without breaking perspective.
They all require more work on DS' part. He could easily have Max follow them and peek in a window. Or he could have Kira ask him to accompany them to the shoot as her assistant.
Considering how much effort into consistency he has showed so far I can easily see him just showing the scene without Max being there...Cause the scene is something he obviously thinks is HOT regardless of how we got there!
I just don't see him wasting the renders on a small screen of the TV.
