because you're checking @IsVisible = '' which corresponds to int value of 0

see this example


DECLARE @i int = 0

SELECT CASE WHEN @i='' THEN '0 is equivalent to blank value' ELSE '0 and blank are not equivalent' END


output
---------------------------------------
0 is equivalent to blank value



Also see

SELECT CAST('' AS int)

output
---------------
0
