I'm a bit confused about the Yeld hiding ability with his wings.

If he makes a normal move in his movement phase, is he allowed to hide?

This is from the rules:
"The chameleonic effect of its wings allows a Yeld to hide even if it is not behind cover; the Yeld simply remains
stationary long enough for its outline to disappear completely."

Almost makes it sound like he has to be stationary in the open, but it also sounds like he can just hide as normal.

Thanks
