You want /home/ABC/www  to be writable by both, but not allow XYZ to modify/overwrite files created by ABC?

Then use the sticky bit

chown abc.ftponly /home/ABC/www
chmod 1771 /home/ABC/www
or chmod +t /home/ABC/www

(That would be a similar stuation as with /tmp... only the file's creator should be able to update the files)

for ABC to access/modify/create content, make him the owner
for ftponly to be able to write to www make that the group and set group write.

In short
drwxrwx--t        ABC  ftponly          ...           www/

In that case, yes, put both users in the same group.

And have the directory owned by the group

and make the mode for /home/abc/www

chown user.group /home/abc/www
chmod 2771 /home/abc/www

(setguid  for a directory means new files will be owned by the same group by default)
