For the idea of an american dealer being chosen 
by the studio for release of cels- another way of 
putting it is like this-
Imagine Disney selling all the cels from their 
newest movie...I don't know, say, the little 
mermaid 2 to a japanese dealer.  A lot of people 
would find that suprising.
The reason is we would think the biggest market 
for such things would be in the U.S., not Japan, 
and wouldn't Americans rather buy from Americans, 
in America?  I believe this is how people think.
