The main point of 1 h4 is to take black out of his comfort zone and force him to find his own moves. It somehow prevents the fianchetto ...g6 and ...Bg7. Sometimes the rook can develop Rh1-h3-x3, a stratagem also dear to Tal.
Your post reminded me of my first attempts to play chess...Only knowing how the pieces moved...I played h-4 followed by r-h3. I then played a-4 followed by r-a3. I was trying to bring my rooks together. I think it did show an attempt for combination play. :]
