Cisco Wireless :: OEAP 600 Series - Maximum User Count

Only fifteen users are allowed to connect on the WLAN Controller  WLANs provided on the 600 series at any one time. A sixteenth user  cannot authenticate until one of the first clients de-authenticates or a  timeout occurred on the controller. Note: This number is cumulative across the controller WLANs on the 600 series. For example, if two controller WLANs are configured and there are  fifteen users on one of the WLANs, no users will be able to join the  other WLAN on the 600 series at that time. This limit does not apply to  the local private WLANs that the end user configures on the 600 series  designed for personal use and clients connected on these private WLANs  or on the wired ports do not affect these limits. This is from the Configuration Guide for teh 600 series Office Extend AP. Is this count per AP or total per WLC? If I have 10 APs deployed to our remote users, can each AP support two simultaneous users? Would I need to use separate WLANs for each OEAP?
