Ok, you can only make a girl squirt with pretty aggressive finger, cock, dildo action on her gspot. You cant do it with your tongue. Those vids you see with girls squirting 10 feet in the air are pissing and pissing hard. When a girl ejaculates she squirts a little out of her skene gland which is the little pad you can feel inside her vagina (upper wall when she is on her back)
Your girl did neither she definately douched herself and pushed the water out when she was cumming. Water will stay up there until she starts cumming and tensing her muscles. Either that or she just lost control of her bladder a little and let out a little piss, but she definately didn't ejaculate (unless you have a very long and aggressive tongue...
