The kernel "remembers" the clients.  Its memory expires after 30 seconds,
I believe.  That is adjustable using sysctl(8); the parameter is one of
these:

net.link.ieee80211.vap0.inact_run = 300
net.link.ieee80211.vap0.inact_probe = 30
net.link.ieee80211.vap0.inact_auth = 180
net.link.ieee80211.vap0.inact_init = 30

probably inact_probe.  Bear in mind that changing the defaults may
adversely affect your connectivity.

The notion of "existing clients" is not well-defined in an ad hoc network,
because there is no "handshake" between adjacent nodes, and adjacent
stations' beacons are not a reliable indication of their presence
or absence.
