As I understand problem is somewhere else.
If this is intentionally unsupported configuration - OK. So why the error
appears ? The directory should be empty then.
If the configuration is unsupported at the moment and the A.txt file is
located on A, some code that attempts to read re-exported files/directories
should be turned off (eg. #if 0).
If the A.txt file is local for B1/B2 hosts, it is (IMHO) an obvious bug.
Sucgh a file should be hidden at the act of mounting. For both local and
remote access.
Neil, could you tell us where the A.txt file is *really* located ?

BTW. AFAIR, I observed similar behaviour (files are visible but
inaccessible) while mounting a local filesystem at a busy directory
(eg.: mount /dev/fd0 .;ls -l) even in 2.2...
