BindingSource.EndEdit and Position

When I call BindingSource.EndEdit on one of the BindingSources of my
application, it correctly finishes the addition of the new row but
surprisingly it also resets its Position to zero (and so also changes the
object referenced by its Current property to the first item on the DataView
that underlies).

I would like to know if this is an expected behavior. It does not happen
with all my BindingSources.

I've handled the BindingSource.CurrentChanged event and I see something like
this in the call stack:

MyForm.bindingSource_CurrentChanged

Thank you very much in advance
