Interestingly enough, I'm showing the same 100% EQM status on my mileage summary, and I'm still traveling. Possibly a retroactive crediting situation -- either way give UA MP a call, and confirm with them that the RTW tix are booked in D-fare seats... ...thus it's implied you will still get the 150% EQM.
I'll let you know if I see any changes on my end. You can bet I'll be pursuing this one as well.
