According to this thread


the author of the assertion control (Kurt :) believes the current 
specification is flawed.  In fact, the assertion control is intended to 
apply to the contents of the DIT.  The entry does not belong to the DIT 
until the operation is completed, so assertion cannot apply.

As per what seems to be the intention of the author of the specification 
(although it is in contrast with the current specification, RFC4528).
