Why do you keep insisting it's an H? It's quite *obviously* an I.

Ultimately, it's just a symbol - on Earth, it's generally used for helicopter pads, and that's cool. But people are creatures of habit, and it's entirely likely that small building-top landing pads for rockets will continue to carry the same logo, just out of tradition.
