Different curves, as you can see.
That's what I expected to see. My Pioneer SC-99 Also has separate EQ for each sub. Some AVRs have 2 sub out connections but they are really just one single signal that is internally split into 2 connections... as if the AVR has its own internal Y splitter. In other cases, like ours, each subwoofer out is independent and is measured and calibrated independently, which would include independent EQ ing if you are using that mode. I believe part of the issue with your system sounding hot, is that when you are listening in pure direct mode, the subs are completely bypassed (bass management is not used), and any EQ that was set during the auto calibration is also bypassed. So now, if in your room YPAO determined that it has to raise certain frequencies and lower others in order to get the best sound (with the speakers set to small so that the bass management is applied), it makes sense that you are going to get very different sound when you listen in pure direct mode which bypasses all of that.
That aside, one thing you should check is the distance settings that the AVR set for each individual subwoofer. It is possible that the subs distances calculated for use in the integration, are causing cancelations for certain frequencies during the calibration, and your AVR is trying to make up for those cancelations by turning up the subs.
I would recommend that you watch these recent videos which speak to multiple Subwoofer integrations. The videos explain different approaches that can be taken, which include using just your current equipment to get the best out of a it, and then for those of us who want to take it a step further and really nail things down properly, there is another video on using REW which allows you take your own measurements and set things properly. They were put together by one of the forum members after helping tons of people get their setup correctly. They are lengthy videos but worth watching every minute if you want to better understand what is going on when calibration is taking place. The videos should help clear up a lot of the questions that have been asked, and even ones that haven't . There's actually a thread in this forum about these videos. He made several other videos including one on gain matching your subs, which you should also watch.
Here are the links to the videos, I hope it helps.
This first link is for the basic setup like yours:
