Yeah, that's it. Not all of the charge pumps use it. It'll actually cause problems for the LT1054. So, if someone wants to use that charge pump in a circuit with the boost connection in place, you have to do something to disconnect it (cut pin 1 or something). The TC7660H doesn't need it either since it's always boosted, but pin 1 is an NC on the TC7660H so it doesn't matter if you leave it connected.
