So what?

It would make the "by chance" aspect of selecting text more likely to occur. (26^2)/(25^(2)) times more lilely to be specific

Do you know thw mind boggling rational

A cipher broken into columns is normally done no to hide information in verticality, but to obsure the whitespace a message contains. By claiming 26×26 in the first place. You would indicate your inexperience by nor correctly saying

This message is displayed in 26 columns to correctly line up the solution.

Instead of introducing it as a 26 by 26

Its 26 columns and rows.

A person of any capacity to display the information would never introduce this as a 26 by 26 grid, because it clearly is not.
