misleading doc typo

on this page:
https://www.openfoam.com/documentation/user-guide/3-running-applications/3.2-running-applications-in-parallel

it gives example of coeffs n (2 2 1);, and then then next line in simple method explains "Simple geometric decomposition in which the domain is split into pieces by direction, e.g. 2 pieces in the x direction, 1 in y etc."
but its actually 2 pieces in x, 2 in y, and 1 in z.

also would be nice to mention that the numbers should match the total number of subdomains: 2x2x1 = 4
