That is exactly what is happening. The clutch tends to disengage when slowing at Approx. 8 mph. Also the throttle on the 650 with all it's feed back sensors is a lot more sensitive then regular bikes. Smaller inputs are needed to achieve the same results. It acts more like an electrical potentiometer. The method used by most experienced 650 riders is to feather in some rear brake along with throttle slightly cracked open to mimic a conventional clutch . The slightly cracked throttle keeps the clutch engaged and the feathered rear brake keeps your speed down. This allows you to perform slow speed maneuvers and turns with much more control and no jerkiness. It is frustrating to the first time rider but with practice it will eventually become second nature to you. So, get out in an empty parking lot and practice.
