I think they meant that deposits made by one player doesn't affect his return. Obviously, the total amount of deposits (incudling purchases of moon deeds and what not) into EU has to affect overall returns. It's the sole source of money to be looted.
The link "I just deposited $200, so now I will get a 4k hof" is just blatantly wrong. Most depositers will lose their money, a few will gain some of their deposits (MU chasers, high efficiency gear and decent looter level), MA will have the rest. Simple as that. A few will get lucky and accidentally HOF right after depo, most won't.
A few players will be unbelievable lucky, like Leeloo or the dude that got away with the 400k mining advertising HOF, or the guy who got 100 tries on juiced BP around xmas (MA's mistake) and ended up with 100k+. They're there to keep the dream alive for the rest of us. And it works.
I've deposited a substantial amount of PEDs through strongboxes, and never looted a ring worth more than 50 ped. Biggest global was 500x (twice, foul young 200 ped, traeskeron alfa 790) after ~200k kills. I am not complaining, just saying that if there was any logic to "I deposit, therefore I HOF", I'd have my uber 1000x HOF and ares perfected a long time ago.
