Well they must not of trusted it or the Crimp Terminals would be yellow not blue LOL
This went over my head!?
In your picture, for 250 V it shows a clearance of (1.25, 6.4, & 0.4) for External conductors uncoated, uncoated >3050m, and coated.
What's the difference between uncoated and uncoated >3050? I get my boards from BatchPCB, they have a solder mask on them, but somehow I don't think that qualifies me to have 250V traces only 0.4 apart! 
Bottom line is: I remove all copper from other side of board, I'll use the largest value there, which is 6.4mm clearance between traces. Then I should be good? (I still don't know how they can have 2 pins next to each other on an SOO8 package having large voltages on them...
