SQL 2012 :: Using Stored Procedure To Truncate Tables?

I was just looking at an SSIS package someone else set up and I went into one of the execute SQL tasks and it is calling a stored procedure to truncate a table. There are a lot of places that tables are truncated within this SSIS package. But each one the 'database', 'owner', and 'table' name are hard coded.

Like this: exec dbo.uspTruncateTable 'dbname', 'dbo', 'tblname'

Of course there are different names, just changed for an example.

Here is the code in the Stored Procedure.

CREATE procedure [dbo].[uspTruncateTable]
@nDatabase varchar(255),
@nOwner varchar(255),
@ntable varchar(255)
as
declare @sqlString nvarchar(max)
set @sqlString = 'Truncate Table ' + @nDatabase + '.' + @nOwner + '.' + @ntable
exec (@sqlString)

This just seems like an unneeded step, just code the 'truncate table dbname.dbo.tblname'.
