Typo in the sdm vol 3

Hello! I apologize if this message doesn't belong to the forum and should have been forwarded somewhere else.
While studying the current version of 'Intel® 64 and IA-32 architectures software developer's manual combined volumes 3A, 3B, 3C, and 3D: System programming guide' taken from this URL: https://www.intel.com/content/www/us/en/developer/articles/technical/intel-sdm.html I encountered a possible typo that can mislead newcomers.
To be exact:
The chapter '4.10.3.1 Caches for Paging Structures' states that bits 56:40 of the linear address are used to search PML5E-cache. But it appears to be contradicting to other information about paging including that which is stated in the very same paragraph ["9-bit value"]. I suppose that bits 56:48 should have been here instead.
Thank you for your attention.
