I would have thought that to be the case, however, I made that choice based on the feed line labeling available in the first flight video. The LOX F/D line seems to be on the bottom of the vehicle, as you can clearly see the aft fin.
The line which separates from the top of the stage appears to have a higher volume, which lead me to believe that this is the LH2 fill line. This is why I guessed at this configuration.
OK, that makes sense. This might be the LOX vent line though.

All boosters/first stages that use LOX have the F/D on the bottom of the vehicle where is interfaces with the vehicle's propulsion system. There is no need to put it up on the tanks and use an umbilical tower. So, your conclusions are not based on relevant data.

When we see the LOX on bottom configuration such as in the Saturn S-II, S-IVB, and Centaur, is there another reason that it's done that way?

For RP-1/LOX rockets, that's the RP-1. For LH2/LOX rockets it's the liquid oxygen.

For LH2/LOX rockets it's the liquid oxygen.Its not always obvious which propellant goes on top. LOX (1.149 kg/L) is denser than RP-1 (0.8 kg/L). For LOX with RP-1 or LH2, LOX is usually at the top for the first stage. For kerosene with High Test Peroxide (HTP or 85% hydrogen peroxide), the kero tank is top, even though kero is less dense than HTP. The reason is the HTP/Kero volume ratio, which is about four to one. The smaller kero tank is top to keep the centre of gravity as far forward as possible.

So thats Shuttle and SLS that got it wrong
Another test in next few days.http://www.parabolicarc.com/2016/01/21/blue-origin-flying/
Third flight coming soon? Tomorrow through Friday, it looks like.

False alarm, it seems. See the post below. Quote from: KSC Sage on 01/22/2016 02:08 pmQuote from: c3infinity on 01/19/2016 03:24 pmThird flight coming soon? Tomorrow through Friday, it looks like.
