TIMESTAMP column description at https://mariadb.com/kb/en/library/timestamp/ has contradicting sentences that may confuse readers.

Second bullet point in section titled "Disabling automatic properties" is as following:

"Specify the NULL attribute. NULL values will now be permitted, and therefore NULL, rather than the current timestamp, will be assigned when the column is set to NULL. Note that, if NULL is permitted, assigning NULL will set the column to the current timestamp."

The second sentence contradicts the first sentence. Should part of the second sentence "if NULL is permitted" be actually "if NULL is not permitted"?
