Correct, from the FAQ. (highlighted relevant part)
Quote:
Q: Do hits stopped by Shields still
cause an additional BM if the weapon
had the Disrupt ability? Similarly do
hits on Grot units by Disrupt weapons
cause an additional BM?
A: Shields and Grots negate the BM caused
by an attack, but are lost themselves in
the process. This means that they do
negate the BM inflicted by Disrupt
weapons.
The same would hold true for any unit,
such as Chaos daemons, that do not
generate a Blast Marker when they are
destroyed.
In effect a Blast Marker is placed either
when the hit is scored or the damage
inflicted, but then the BM is removed when
the shield goes down or the Grot is killed.
Note that in both cases there is no save
allowed against the hit, so any hit will
automatically result in the shield or Grot
being lost.
So any unit (or void shield/power field) that normally negates a BM when it dies (goes down) keeps the BM if it survives. IIRC reasoning at the time of discussion was that grots/'Guants (making cover saves) and daemons etc that survived would still be disrupted from the attack even though other units in the formation don't care if they die. (Epic-UK tyranids should be affected in the same way but the E-UK rules committee when asked about this previously stated that the 'gaunts that survive a disrupt attack don't generate BM's, so for me that list plays it differently to others.)
Holofileds are a bit different, if the save is made then the BM is negated, reasoning being the attack has landed where the Titan isn't so a disrupt hit wouldn't affect it as it didn't hit the titan but where the attackers thought the titan was.
