Grammar question (proving that Snape is evil?)

Hi!

I was surprised about a sentence DD told Draco on the tower, but maybe
it is a stupid sentence (English is not my first language...).

DD: "I asked SS to watch over you..."
Draco: "He was protecting me because he made an UV to my mother"
DD: "This is what he may have told you, but"

MAY have told you? Well, it was the truth, wasn't it? Whatever SS was
doing on DD's orders, his primary goal in watch over DM was to fulfill
the UV and thus save his own life.

I've been trying to understand if indeed that "may" suggests that DD
didn't know about the UV...mmmh, let's take this situation, SS is a
diabetic and DD, for his own motives, asks him not to eat sugar: we have:

DD, "SS is not eating sugar on my orders"
DM, "foolish man, SS is not eating it because he's a diabetic"
DD, "now, this is what he may have told you, but"

This doesn't seem right to me. This seems right only if DD didn't know
about him being diabetic. If he'd known, he would have said:

DD "Yes, of course he is, but I gave him precise orders", or something
like that.

What if DD didn't know about the UV? What if SS was to keep an eye on
DM PREVENTING HIM from going too far? But SS, bound by the UV, argues
with that (the struggle in the forest), not daring to confide his true
motives (ie, he'd be killed if he stops DM).
Then we have the following scenary:

a) Snape is good, not matter what, he didn't tell about the UV for his
own motives and he's going to help HP somehow

b) this proves SS is evil, full stop.
