Latin1_General_BIN comparing two char strings

My database is Latin1_General_BIN.
My table is called CUSTOMER.
One column in this table (descr_id) is defined as char(10).

When I query=85

SELECT *
FROM CUSTOMER
WHERE descr_id =3D =91ABCD=92

Result set from above query is:
descr_id
ABCD

I get the same result back as I do when=85
SELECT *
FROM CUSTOMER
WHERE descr_id =3D =91ABCD      =91 (notice ABCD string has padded
spaces).

Result set from above query is:
descr_id
ABCD

Does anyone know why this is the case? I would expect second query to
not to return anything.

Many thanks,
Igor
