Both sides work for this trade now. Funding pays +$1 a day on $10k at the current rate, and Phemex is 0.123% dearer against Reya than usual: you sell high and buy low: +$12 more if the spread goes back to its 7-day average of +0.015%. The two prices were read 46 seconds apart, so part of this spread may be the market moving, not a spread.
