The key noteable in the EAS test was in the wording... the United States AND Washington DC
Don't let that detail slide by you..
Edit:
Video of live feed as it happened:

Recorded on OTA antenna, the signal started to break up as the EAS started.
Glad i recorded it cause different states got slightly different messages i guess.
Same wording on tv here. Noticed it right away. US and DC were on separate lines.
Glad i wasn't the only one who got that.
I find that very telling.
