As I recall, Snape's reaction happens right after Harry names Lucius 
Malfoy.  I think this is the telling part of the moment.  Now as to 
WHAT precicely it's telling, well, only Jo knows for sure.

My current theory (based on one part instinct and two parts pulling 
it out of my--hey-HEY!) is that Snape, for reasons we can at the 
moment only speculate at, believes (or wants to believe) Lucius' 
story that he (Lucius) was aiding Voldemort against his will.  When 
Lucius' name is the first one Harry gives, Snape's initial reaction 
is disbelief, perhaps an inclination to contradict the accusation, 
but in the presence of the others he thinks the better of it.
