Pippin:
If wand function is supposed to be intuitive and/or mechanistic, then JKR failed. But  Ollivander consistently describes wands as subtle and sentient devices. That Voldemort doesn't  understand this leads to his downfall, so it seems to be a carefully thought-out part of the plot.  

Viewing the world as his personal toybox, Voldemort is not about to respect the opinions of a mere object. 

But clearly wands rely on their own interpretation of events, and it's up to them to decide whether or not an attack must be taken seriously. As each one is unique, they may not all respond the same way to the same circumstances. 

Hermione takes the Trio's expelliarmus attack on Snape  seriously in PoA, whereas Snape himself dismisses it. Fortunately for Snape, it seems his wand agreed with him. But notice that Sirius is careful not to attempt any powerful magic using Snape's wand except in concert with Lupin.
