I was confused, the cores should be filled (act as a key), but not the
cavity.

That said, still cheap and thin.  (Am I describing masonry here?)

steve,

yeah, I don't quite buy the hole in the brick being meant for 
ventilation, yes on saving weight and a little bit on raw materials
and the few times I worked on a brick line (never got past lunchtime) I 
got the impression the intention was for the mortar to go in the holes 
for additional holding
no way in Hades anyone gonna lay a brick w/out getting mortar in the holes
