 yes. There are examples of this in the spec are there not?

Neither.

foo[position() < $limit AND bar AND last()] 
       

isn't what you meant, you meant
foo[position() < $limit and bar and position()=last()]    

in this one last() would return the number of foo elements.

(((foo[position() < $limit])[bar])[last()]) 

In this case this is equivalent to
foo[position() < $limit][bar][last()]


as foo is short for child::foo which is a forward axis.

But for a reverse axis, 

ancestor::foo[position() < $limit][bar][last()]

last() and position() relate to reverse document ordering but in

(((foo[position() < $limit])[bar])[last()]) 

last() and position() relate to document ordering
