easy ...truncate resets the identity;

It's a coincidence , I was just discussing it with my colleague about inserting a row in between identity inserted column. And yes, Truncate popped up as an option 🙂

I'm also wrong, but i learned something. Could someone please explain, why is the identity resetted after a truncate? For me is a possible source of inconsitency.

TRUNCATE command apart from removing data from the table, resets the seed value of the identity column defined in the table.

Another command to re-seed identity is DBCC CHECKIDENT. It can be used something like below:

DBCC CHECKIDENT ('test_trun', RESEED, 0)

Not sure why you said this as "inconsistency"...it's just the property of TRUNCATE command!

bcoz it is its behavior that every time we execute TRUNCATE command it will reset the identity value..
