To be very clear, the most likely course of events is as follows:
Vendor B puts in a transfer request to ARIN for a /16 and it is 
denied because they only need a /20 under current policies.  They
reapply to transfer specific /20 from vendor A (which concurs) and
that is approved and the registry is updated to reflect that the
specific /20 is now held by Vendor B.

The remainder of the /16 is remains registered to vendor A.

Vendor B can certainly submit a second request at a later time; 
we would ask for concurrence from Vendor A before we processed
the request.

I hope this helps,
