It's a bit of a stretch. FEMA describes most of that advice as a last resort: if you feel a tingle, and you are in the open, then assume that position, meant to minimize damage.
On the other hand, FEMA and all other sources that I've seen clearly spell out that you need to find shelter, and that's the best way to ensure your safety.
If you feel your hair stand on end (which implies that lightning is about to strike), squat low to the ground on
the balls of your feet. Place your hands over your ears and your head between your knees. Make yourself the
smallest target possible and minimize your contact with the ground. DO NOT lie flat on the ground.
During Thunderstorms and Lightning
If thunderstorm and lightning are occurring in your area, you should:
- Avoid hilltops, open fields, the beach or a boat on the water.
- Take shelter in a sturdy building. Avoid isolated sheds or other small structures in open areas.

How to survive a lightning strike
The best way to survive, of course, is to avoid a lightning strike.
The Federal Emergency Management Agency (FEMA) recommends people
follow the 30/30 rule: If, after seeing lightning, you can't count to
30 before hearing thunder, get inside a building immediately (because
the lightning storm is close). And don't go outside until 30 minutes
after the last clap of thunder.
If you're caught outdoors in a forest during a lightning storm, seek
shelter in a low area under a dense growth of small trees. Avoid tall
trees, since lightning tends to strike the tallest object in an area.
If you're in an open area, go to a low area, like a valley or a ravine
(but be alert for flash floods). If you're in a boat in open water,
get to land as quickly as possible.
And if you feel your hair stand on end, that means lightning is about
to strike. As a last resort, immediately squat down on the balls of
your feet, cover your ears with your hands (to minimize hearing loss)
and put your head between your knees.
