Blood Bernard-Soulier; why thrombocytopenia?

FA 2011 pg. 355

Bernard-Soulier has decreased Platelet Count... why?
Platelets can't bind to the endothelium, thats the defect. Nothing to do with a decrease in platelet count.

ITP and TTP i can understand because they are being destroyed and are consumed in thrombosis.

I actually remember asking the same question in class months ago and couldn't think of the answer I I searched:

It is a type of Giant Platelet syndromes and due to the possibility that when the platelet count is performed with automatic counters, giant platelets, which may be as frequent as 70–80% in occasional patients, may reach the size of red blood cells and, as a consequence, are not recognized as platelets by the counters.
