From NIST SP 800-63B, Is this a conflict or am I reading it wrong?

"When processing requests to establish and change memorized secrets, verifiers SHALL compare the prospective secrets against a list that contains values known to be commonly-used, expected, or compromised. For example, the list MAY include, but is not limited to:
• Passwords obtained from previous breach corpuses.
• Dictionary words.
• Repetitive or sequential characters (e.g. ‘aaaaaa’, ‘1234abcd’).
• Context-specific words, such as the name of the service, the username, and derivatives thereof."

But then it goes on to say:
"Verifiers SHOULD NOT impose other composition rules (e.g., requiring mixtures of different character types or prohibiting consecutively repeated characters) for memorized secrets."

So on the one hand they are saying check for repetitive characters but then saying one should not impose composition rules that prohibit repeated characters??

Also mixed character types should no longer be used (alpha numeric caps_lower)?
