WE8ISO8859P1 convert to AL32UTF8 unicode character set question

I have one question about CSSCAN when I do conversion from WE8ISO8859P1 to AL32UTF8 unicode character set.

create table aaa (c1 varchar2(10));
insert into aaa values ('sys.…Med');

After csscan the data, get the application exception data as below

User  : JACKY
Table : AAA
Column: C1
Type  : VARCHAR2(10)
Number of Exceptions         : 1
Max Post Conversion Data Size: 9
ROWID              Exception Type      Size Cell Data(first 30 bytes)


------------------ ------------------ -----

------------------------------

AAAYtgAAEAAAEKPAAA lossy conversion         sys.…Med


------------------ ------------------ -----

------------------------------

But after use convert method and check it, the data can be converted successfully after use below sql

select case when convert(convert(C1, 'AL32UTF8', 'WE8ISO8859P1') ,'WE8ISO8859P1', 'AL32UTF8') = C1 then 0 else
-999999+111111 END from aaa;

Is report of cssacn not correct?
