Hard to read because you cannot see the column names when looking down the list.
How to repeat:
read http://dev.mysql.com/doc/mysqld-version-reference/en/mysqld-version-reference-optvar.html
jump to a random variable and tell me what all the NO, YES means without scrolling to the top and losing your place, or without remembering each column.
Suggested fix:
Look how vmstat does it. it reprints the column names so they are visible on your screen.
[root@localhost 5.7]# vmstat 1
