Cocos2D iPhone - will this save memory?

When you create a sprite on cocos using a texture you allocate memory.

Something like:

CCTexture2D *textureProxy = [[CCTexture2D alloc] initWithImage:image];

CCSprite *proxy1 = [CCSprite spriteWithTexture:textureProxy];

My question is: suppose I want several sprites using the same texture and I do

CCSprite *proxy1 = [CCSprite spriteWithTexture:textureProxy];

CCSprite *proxy2 = [CCSprite spriteWithTexture:textureProxy];

CCSprite *proxy3 = [CCSprite spriteWithTexture:textureProxy];

CCSprite *proxy4 = [CCSprite spriteWithTexture:textureProxy];

CCSprite *proxy5 = [CCSprite spriteWithTexture:textureProxy];

Will I use 5 times more memory? (or in other words, will the texture be duplicated to each proxy or is the sprite just a "empty box" that references the original texture?

If the later is the answer, then the memory usage for similar sprites are not that huge, right?

thanks.
