second one- sorry...
That's okay! That's what I thought, I just didn't want to answer you the wrong way

.
Euphemisms are generally used to adhere to politeness principles - even if you are using euphemism to confuse the audience, there is still an association to what the user is really saying.
It's like someone saying "I'm going to powder my nose" when they need to go to the bathroom - they are obfuscating the truth of what they're actually doing to be polite and avoid taboo (making themselves look better). But the audience still knows what they actually mean.
Euphemism is changing meaning, but it's not completely dissociated from the denotation (it's just a different and more polite way of saying things).
Doublespeak, on the other hand, is active deception. It's using words completely separate from the actual meaning to deceive the audience of events that have happened in order to make the user, their actions or their subject more palatable.
This is like the T-Abs immigration department exclusively using "illegal maritime arrivals" or case numbers to refer to asylum seekers they are processing. It is deliberately removing the human element from "asylum seeker", "refugee", "boat people" and all that to make their actions easier for the workers to process (as they are just combating illegal action and not people).
It's also like advertisements using "natural flavors" to talk about their food - we don't know what the heck 'natural flavors' really are, we just know the connotations of 'natural' being good, fresh, etc. and that's all we hear (these are also called 'weasel words').
Hope this helps!
