Steps to repro:

1. Create the following sample table and FTS catalog on your SQL Server
   

   CREATE TABLE dbo.test_table(column1 INT identity(1,1), column2 NVARCHAR(MAX))
   ALTER TABLE dbo.test_table ADD CONSTRAINT PK_TB_Test PRIMARY KEY (column1)
   CREATE FULLTEXT CATALOG [test_Cat]WITH ACCENT_SENSITIVITY = ON
   CREATE FULLTEXT INDEX ON [dbo].[test_table] KEY INDEX [PK_TB_Test] ON ([Test_Cat]) WITH (CHANGE_TRACKING AUTO)
   ALTER FULLTEXT INDEX ON [dbo].[test_table] ADD ([column2] language 0)
   ALTER FULLTEXT INDEX ON [dbo].[test_table] ENABLE
   GO 
   

2. Populate the table with the following sample data
   

   insert dbo.test_table(column2) 
   select N'4050300948' N'4050300948'
   union
   select N'4050300552' N'4050300552'
   union
   select N'4050300423' N'4050300423'
   go
   

3. Execute the following queries: 
   

   select * from dbo.test_table where contains(column2,N'4050300164',LANGUAGE 1033)
   go
   select * from dbo.test_table where contains(column2,N'4050300164',LANGUAGE 0)
   go
   
   

   You will notice that the first query returns no results because it uses English word breaker but the second query returns three false positives because it is using neutral language word breaker.
