whats the deal w/ ATF in fuel filters?

i've been reading all these old posts and filling your spin-on with ATF seems completely acceptable, even recommended. this sounds like a completely ludacris thing to do but i assume it isn't, seeing as a few of you seemingly trustworthy and knowledgable guys condone it. my question is why should i do this rather than filling it with diesel? while i'm at it, another question:
what the heck does the ALDA looking thing on my IP do on a non-turbo 240?
and another:
why can't i get that last little air bubble out of my primary? (clear) fuel filter?

The theory is that the ATF will help lubricate the injector pump and clean the injectors. I say theory because I've heard several diesel mechanics swear by it. On the other hand I've read several articles saying it does not do any good what so ever. I used to do it regularly as a maintenance procedure, myself, but have since ceased. I do still use the ATF to fill the canister filter, during replacement, for a couple of reasons. I usually don't have the diesel lying around as where I do have ATF. ATF will readily burn as fuel in a diesel engine. For me it's just easier.
