Actually to me DD explanation about Snape being surprised Harry still 
believed Sirius was still a captive of LV, has everything to do with 
the animosity between them. So to me it seems Snape told this to DD 
to put the blame back with Harry because it was Harry's fault, he did 
not trust Snape enough to look into things and thus letting go of it 
and Snape truly believed Harry should have thought that highly of 
Snape, that it would be only Snape and not Harry that would solve the 
situation. To me it looks like he washes himself from blame or 
responsibility for Harry state of mind at that moment. 
It is not like he couldn't have known Harry would not have trusted 
him not even if Harry tries to alert him. With a response Snape gives 
him like that who would have believed Snape would do anything. 

Harry is even desperate enough to want to try and allert Snape so 
should have known this or at least I feel so. 

Snape never did anything between the time he (supposedly) checked in 
on Sirius and the time he alerted the Order again. He could have gone 
back to Umbridge with another bottle of fake serum with the excuse he 
found some stashed away and forgot about, he would have made her day. 
He could have stayed in the vicinity or come back right after he 
checked in with Sirius, then he would have seen the IS was defeated 
or even see those four kids leave the Hogwarts Grounds into the 
Forest. But he doesn't, he only realized Harry left to the DoM after 
Harry already arrived there and already spend some time there. When 
did Snape start worrying? After it getting Dark and still no sign of 
Harry? To me it seems like it and this indicates to me, a total 
inaction on Snape's part to keep an eye out. What does he care if 
Umbridge tortures Harry a bit, he probably would gloat at the idea. 

How long would it have taken the Order to have apperate to the DoM 
from GP, both are in London? It would have taken no more then 
minutes, so let's say after leaving instruction with Kreacher, it 
takes them 15 minutes to get there, this still takes longer then 
Harry and his friends to fly over there. That is why Snape actions do 
not fit, either by is own reluctance to keep an eye on Harry more 
closely or for more evil reasons, it still makes Snape actions 
responsible for a lot of what occurred that night.  

Snape not only could have done more, he should have done more. 

If this was not written on purpose, then it was indeed sloppy writing 
on JKR part. 

JMHO
