Coincidence??

Right now my ponies and Kimfer's two are living in a nice little pasture. Just before finals however there were just my three living in this particular pasture. And every time I went in the gate I'd whistle and call their names. I'd also give the gate chain a rattle for good measure. I'm trying to teach them to come when they're called so there are treats involved as well.
Every time Voodoo would come to me first with Applejack and Cessa following along. They'd all get cookies and rubs and scratches and talked to (I talk to my horses like they know what I'm saying... actually to all my critters) before catching whoever was needed.
One day the neatest thing happened, it was probably a coincidence but was still pretty darn cool! When I went in the gate and did the usual whistle/rattle/call routine Voodoo came loping over with Applejack trotting behind. No Cessa. I wasn't too worried, when I drove by the pasture I had seen the boys were right on the other side of a bush by the gate. Cessa was probably just a little farther away.
While I gave them their cookies and scratches I kept calling Cessa. Voodoo had gotten his share and I was petting Applejack while still calling for my girl.
Suddenly Voodoo took off at a quick lope.
I thought to myself "hmm... okay guess you're feeling ignored!" and kinda chuckled.
But then a second later he came trotting around another bush with Cessa at his flank!! :o He trotted right up to me and looked SO proud of himself!
Of course I had to give him an extra cookie and rub and tell him what a good boy he was while giving Cessa her cookies.
Like I said, probably a coincidence but still darn cool!
