The Word Wood

The current assignment I'm studying in my Simplified Functional Manual are the vowel sounds: w, sw, wh.

One of the words in my reading lesson is the word "wood".

The word WOOD

Usually when I come across a new word when I study it I sound the strokes out loud. But, I really don't understand why the beginning of the outline has TWO small upside down hooks instead of one. They look more like the small hook that I just learned for the sounds as in the words up, foot, food.
