They both do the same thing, since a repeat object is a single item  
binding:

"a repeat object consisting of an implicitly generated group element that  
binds to the item, and containing a copy of the template."

I thought about this, and I can think of no place except for bind where a  
sequence binding is nested directly within a sequence binding.
