TL;DR: Correctly.
In detail: Multiple processes indeed share the acceptor socket,
but only one (otherwise) idle process at a time is monitoring it
for new connections. The rest (of the idle processes) are blocked
on a file lock, which is released by the lock holder once it accepts
a connection to process (and is no longer idle).
