can another user 777 and existing 777 dirctory?

User usrA creates dirA directory and runs chmod 777 on the directory. Can usrB issue another 777 on dirA? It appears the answer is no even if the usrA and usrB are part of the same group. I know this is a rare scenario but I just ran across it and found out that usrB receives an error when attempting issue chmod 777 on an already 777 directory owned by usrA.

NAME
rfmkdir - make remote directories SYNOPSIS
rfmkdir [ -m mode ] [ -p ] directory... DESCRIPTION
rfmkdir provides an interface to the shift remote file I/O daemon (rfiod) for creating remote directories in mode 777 (possibly altered by umask(1)). The directory argument is either a remote directory name of the form: hostname:path or a local directory name (not containing the :/ character combination). Creation of a directory requires write permission in the parent directory. OPTIONS
The following options apply to rfmkdir: -m mode This option allows users to specify the mode to be used for the new directories. Choices for modes can be found in chmod(1). -p With this option, rfmkdir creates dirname by creating all the non-existing parent directories first. SEE ALSO
mkdir(1), umask(1), mkdir(2), rfiod(1) AUTHOR
