The paragraph you are referring to must be this one:
"When using the socket-dir option, it is generally necessary to specify
socket-dir or socket-dirs on all following commands,
for xpra to work with the open sessions."

It just means that if you choose to place your sockets in a non-standard
location when starting a server (ie: --socket-dir=/tmp) then you will
need to specify the same socket-dir option to interact with those
already "open sessions" with all subsequent commands ("xpra attach",
"xpra list", etc)

Multiple user accounts can also access the same session via TCP.
For unix domain sockets, you can add your users to the "xpra" group and
a socket will be created in /run/xpra.
That alone is not sufficient: you also need to change the socket
permissions to allow other members of the xpra group to access this
socket. (see mmap-group and socket-permissions)
You may or may not want to add authentication to that socket, see the
"auth" switch.

Finally, make sure to enable sharing if you want your users to access
the same session concurrently.

Open sessions is synonymous with "active sessions" here.
That's all there is to it. "xpra list" will show you the list.

The sharing support and options are much improved in version 2.x
