This depends on *how* the client is disconnected, and how it was connected
to start with.
On a TCP connection, the server knows (because TCP goes away).
On an UDP session, the server can't know whether the client has been
disconnected or is just "not sending anything", so how long it will take
to update the status file depends on the "keepalive" settings (no keepalive
= it might never update the status) and whether or not the client is
using "explicit-exit-notify" <<- "tell the server the client was
shutdown".
But even if explicit-exit-notify, it might run into timeout delays, if
the client is not properly disconnected but the machine crashes, the
internet router dies, ...
So, yes, this is the way it is. If you think this is a problem, be
more specific, like "client config, server and client log when the
client disconnects (both with --verb 4), etc"
