I am not wrong
Yes you are.
If you need more proof than the rule book, watch the punt return by LSU's Trindon Holliday in the 4th Quarter of the Capital One Bowl on January 1, 2010. On the play, he made a vague, below-the-waist hand motion that was correctly ruled to not be either a valid nor an invalid fair catch signal.
If you were right, the ball would have been dead at the spot where he caught it. You're not, but I imagine you'll continue to cry about it.
Boo hoo.
