I understand your point, Ron. But there are two things unknown. Let's dismiss one of them by assuming that a worker standing between the two switchboards can walk in a direction that is "downwards" as shown in the sketch, and leave the area. That would give us one of the two required exits from the working space.

The other unknown is the size of the column. Simple math tells me that the area between the two working spaces, as shown in the sketch, is 8 inches wide. But since the required working space is 48", and not the 42" shown, the two working spaces will overlap by 4 inches. That is acceptable. But now if you work on the board to the left, and need to leave quickly, and first step away from the board on the left far enough to be past its working space, and turn in the direction of the top of the page, will you have 24" of space between the edge of the left-hand board's 48" working space and the column? If the column is drawn to scale, I would say no. The column looks like it is more than half the width of the 42" working clearance shown on the right hand board.

Here's the math: There is 7'-8" between the boards. 4' of that is the left-hand working space. That leaves 3'-8", or 44", between the end of the left-hand working space and the right-hand board. The column appears to take up at least 21" of that space. This leaves only 23", and probably less, of clear space to walk past the column. It is close to being compliant. But as drawn, without more detailed measurements, I would not accept it.
