'Realism' is a flimsy excuse for changing the rules in a game that features the bizarre range of character types and challenges that D&D does.
As far as moving diagonally between two figures, it's consistent. Look at the way Wall AEs are defined. A 'wall' can't just be along a diagonal, each square of the wall must be adjacent to two others. If you want to lay out a line of creatures meant to present a similar, though living, barrier, you'd have to place them the same way. The mistake isn't in letting you move diagonally, the mistake is in leaving that gap in the 'line.'
Just a quirk of using the grid.
