Yet Dumbledore says to Harry at the end of OotP: 
"I have already said that it was a mistake for me 
not to teach you myself, though I was sure, at the 
time, that nothing could have been more dangerous 
than to open your mind even further to Voldemort 
while in my presence--"

This suggests to me that Dumbledore was fully aware 
of the methods Snape was using to teach Occlumency to 
Harry and that they were the same methods Dumbldedore 
would have employed himself had he been the one doing 
the teaching.

I'm not sure that Snape was deliberately holding back 
while attempting to teach Harry.  It may really have 
been just his personal baggage that got in the way 
despite a sincere attempt to succeed. But if he was, 
it is easy to see why.  If it would have been dangerous 
for Dumbledore to open Harry's mind even further to 
Voldemort in his presence, how much more dangerous 
was it for Snape, whose only protection from Voldemort 
is Voldemort's lack of knowledge about just how good 
an Occlumens Snape really is.
