I look at this as soaking the grains rather than using the grains for a filter like on a "traditional" mash tun. It really shouldn't matter where the wort goes as much with BIAB. Maybe I am wrong
You are correct. In BIAB, the bag or basket serves as the filter, not the grain bed. You really only need the grain to be wet and consistent in temperature to convert, then your focus is on ensuring you capture all of the liquid (not leaving the sugars behind). When you are sparging, you typically want the liquid to flow uniformly so that parts of the grain bed dont go unrinsed. That is a non-issue with BIAB, as you are (normally) already at your full volume.
