Iterating over mounted objects

In SceneObject.cpp, I've just come across this:

for ( SceneObject **ptr = &mMount.list; *ptr; ptr = &(*ptr)->mMount.link )

And was wondering, would it not be more readable to write:

for(SceneObject *ptr = mMount.list; ptr; ptr = ptr->mMount.link)

It's a really minor point, but I'm also kind of wondering whether my shorthand is actually correct code. I'm using it to scope mounted objects, and it doesn't seem to be breaking anything so far!
