Arduino connecting grounds

Hi all,

I have a question here, which is probably simple to some of you, but I'm going to ask it anyway.

When using multiple servos from an Arduino, I use an alternative power, to the Arduino's on board power, however Arduino and servo power all derives from the same battery. I also connect the grounds, from the servos to a ground on the Arduino. I assume this to be correct, as it works and all the information I have viewed supports that.
