RLS not working

[Daniel29195]

Hello,
im testing the dynamic RLS, 
i have the following table. 

RLS formula 1 ; 

VAR _key =
CALCULATEtable(
values('Table'[empid]),

'Table'[adress] = username())

RETURN
PATHCONTAINS('Table'[emppath], _key )

testing RLS on test1 :  test1 , should see all other users. ( the above code doesnt worrk)

RLS formula 2 : 
VAR _key =
CALCULATEtable(
values('Table'[empid]),
filter(
'Table',
'Table'[adress] = username())
)

RETURN
PATHCONTAINS('Table'[emppath], _key )

with this code, 
the RLS works. 

so im confused about why the first code didnt work .

any help explaining the reason why the first code didnt work correctly, but the second did would be appreciated,
