On 802.11-2012 Std. Page 475, On IE list:

SSID List (see 8.4.2.75) 84 2 to 257
Multiple BSSID-Index (see 8.4.2.76) 85 3 to 5

AFAIK it's introduced reduce the overload of multiple beacons on VAPs configurations. I don't know when it was introduced but it seems usefull, and probably implemented on advanced routers ( Cisco, Aruba etc... )?
If Kismet receives this kind of IE, it will detect one BSSID ( it will detect the "real" AP ) and will detect the rest of bssids with data or other frame types, so probably it doesn't matter too much.
