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.
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.
