Yes this is how alignment is implemented. The bounding lines - in your 
example the top of the selection bounding box is calculated and used to 
align the objects on it. The same algorithm is used for left, right and 
bottom alignment.
For middle alignment the reference line is in the middle of the selections 
bounding box.

The "cheating" would involve an extra object, which has to define the top 
and bottom of the overall bounding box. And it would have to be already 
middle aligned with the object you want to have fixed.

Locking an object would need some special marking within a selection and I 
can't think of a good (i.e. obvious) user interface reflection of that.

One way which could allow the user to influence the reference position for 
alignment would be the order of selecting objects, e.g. we could define the 
very first selected object wont move. But I think that behaviour would be 
less obvious or understandable than the current behaviour.
