How can the same user have logged in to two controllers (Zone Director and Virtual SmartZone) at the same time?

Hello,

How can the same user have logged in to two controllers (Zone Director and
Virtual SmartZone) at the same time?

 FreeRADIUS Version 2.2.3
 Virtual Smartzone High Scale: 3.6.0.222
  Zone Director ZD3025: 9.12.3.0 build 105

We were migrating the APs from ZD to VSZ, but as the pandemic emerged and
everyone is at home now, we stopped the migration and the two controllers
are in operation.

In the corresponding radacct of each controller, I found the chronological
order:

Tue Jun 9 09:47:11 2020
Acct-Session-Id = "5EDF8325-2E943C01"
Acct-Status-Type = Start
Acct-Authentic = RADIUS
User-Name = "x"
NAS-IP-Address = IP_VSZ
NAS-Port-Type = Wireless-802.11
Connect-Info = "CONNECT 802.11b/g/n"
Event-Timestamp = "Jun 9 2020 09:40:07 -03"
Ruckus-SSID = "Y"

Tue Jun 9 09:48:45 2020
User-Name = "x"
Acct-Status-Type = Start
Acct-Authentic = RADIUS
NAS-IP-Address = IP_ZD
NAS-Port-Type = Wireless-802.11
Connect-Info = "CONNECT 802.11g/n"
Acct-Session-Id = "5C108A3D-0458941E"
Acct-Multi-Session-Id = "2ce6cc39d168687d6b0eb2b35edf852cc33a"
Ruckus-SSID = "Y"
Event-Timestamp = "Jun 9 2020 09:48:45 -03"

Tue Jun 9 09:55:40 2020
User-Name = "x"
Acct-Status-Type = Stop
Acct-Authentic = RADIUS
NAS-IP-Address = IP_ZD
NAS-Port-Type = Wireless-802.11
NAS-Identifier = "2C-E6-CC-39-D1-68"
Connect-Info = "CONNECT 802.11g/n"
Acct-Session-Id = "5C108A3D-0458941E"
Acct-Multi-Session-Id = "2ce6cc39d168687d6b0eb2b35edf852cc33a"
Ruckus-SSID = "Y"
Event-Timestamp = "Jun 9 2020 09:55:40 -03"
Acct-Terminate-Cause = Idle-Timeout T
imestamp = 1591707340

Tue Jun 9 10:08:06 2020
Acct-Session-Id = "5EDF8325-2E943C01"
Acct-Multi-Session-Id = "743e2b370028d077146daa375edf8325ba1a"
Acct-Link-Count = 1
Acct-Status-Type = Stop
Acct-Authentic = RADIUS
User-Name = "x"
NAS-IP-Address = IP_VSZ
NAS-Port-Type = Wireless-802.11
Connect-Info = "CONNECT 802.11b/g/n"
Event-Timestamp = "Jun 9 2020 10:01:02 -03"
Ruckus-SSID = "X"
