Since people are twisting the intent of the blast shape, I suppose twisting has to be done a bit more to get them to see the light.
The following is the definition of side.
Side - one of the surfaces forming the outside of or bounding a thing, or one of the lines bounding a geometric figure.
This is the blast area of a power as defined by the PHB.
Blast: A blast fills an area adjacent to you that is a
specified number of squares on a side. For example,
the wizard power thunderwave is a blast 3, which
means the power affects a 3-square-by-3-square area
adjacent to you. The blast must be adjacent to its origin
square, which is a square in your space. The origin
square is not affected by the blast. A blast affects a
target only if the target is in the blast’s area and if there
is line of effect from the origin square to the target.
So since you can CLEARLY see one of the sides of is well over the 3 squares ( in this case) limit, it does not meet the parameters.
That is not a side.
It is a diagonal. From your own definition of a side, a side is an outside boundary, not an interior one. There is no diagonal limitation in the rules (TMK).
You seem to be strongly opposed to a literal reading of the rules in this case.
"Blast: A blast fills an area adjacent to you that is a specified number of squares on a side. For example, the wizard power thunderwave is a blast 3, which means the power affects a 3-square-by-3-square area
adjacent to you."
3 square by 3 square (note: not 9 squares, 3x3). Check.
"The blast must be adjacent to its origin square, which is a square in your space."
Adjacent to origin. Check.
"The origin square is not affected by the blast."
Origin not affected. Check.
"A blast affects a target only if the target is in the blast’s area and if there is line of effect from the origin square to the target."
In area and line of effect. Check.
We are definitely twisting the intent. I agree with that statement of yours. But, we are looking at RAW here, not RAI.
