Switch off works, even if Android phone is lock.

I have Android 4.2 Jelly Bean, I has set it to auto-lock after 10 sec of in-activeness. After it get lock, still i am able to Switch off my Phone, if i long press the side unlock button of my phone, for around 3 to 4 sec. i.e It gives me option to Switch off the phone.
If my Phone is lock, than i don't want somebody/myself to switch off my phone,even if i long press the side unlock button of my Phone.

This doesn't happen in other Nokia E63 phone, than why it happen in Android phone?

Because that's how it's designed. I don't know of any Android device that can't be turned off when it's locked. I wouldn't worry about doing it by accident. As for someone else doing it, I'm not sure why you're concerned, but you may have to just live with it.
