An aura issues forth from each side of your space, emanating out to a specified number of feet in all directions. For instance, the bless spell’s aura radiates 30 feet from the caster. Because the sides of a target’s space are used as the starting point for the aura, a Large or larger creature’s aura affects a greater overall area than that of a Medium or smaller creature.
The rules for cover apply to auras (see page 314); an aura does not need line of effect to a target, but it must not be entirely cut off from the target (an aura in a lead box would not extend outside the box). Some auras are active for a duration, meaning you can potentially move while the aura is active; in this case, the aura moves with you as you move.
Right now with this wording, this means that as long as the area is not completely cut off from the point of origin from the aura, it will effect that area. This is due to auras in 2e lacking the spread rules from 1e.
Essentially, no matter how far you walk, as long as you end up within the radius of the aura without needing to go through a solid wall, that area is considered to be a part of the aura.
Instead, we could make the edge of the aura be considered a wall

This clearly states how they work and helps clear it up.
Edit: Relevant Image Currently the ? case on the left is included, this change would fix that.
