Yes, that is correct. 0*2 is always going to be zero!
If you want to be a butt-kicking healer, might I suggest Favored Soul from the CD? You can pick up all the healing/vigor spells and all the summoning spells and still have a boatload leftover for other stuff.
Here's why I suggest it:
1. Vigor spells are much more powerful than cure spells, but are most effective once the combat is over. This is because the vigor spells heal over time. Cure spells heal fewer hitpoints than their vigor counterparts but are excellent in-combat spells. With Favored soul you could put the vigor spells on your list for the levels they are there and put the cure spells on your list on the other levels. That way, you would always be able to have the right trick for the right time.
2. The Favored Soul boost to saves, equal hitpoints, equal BAB means that if you want to be able to heal and do other stuff you might be more effective than a cleric. Most DMs (myself included) do not let clerics (or anyone) spontaneously cast Vigor spells. So, you might have to occupy slots with those. As a Favored Soul, who cares? If you need it, you got it. If you don't, cast something else.
3. Favored Soul 15 / Thaumaturgist 5 works well, especially if as a Favored Soul you also put the summoning spells on your list. If you put the summoning spells on, you become the guy who gives the meat shield an easier time, the guy who heals, the guy who can set up flanking without putting anyone in danger, and a decent fighter in your own right. If you put the Thaumaturgist on top of that, it is really nice.
I'll admit. The delay in spells is a bit unfortunate, but in my opinion you'll make that up by the end and your versatility to fill the common expectations plus do what you want will give a fair amount more satisfaction.
Just a thought, though.
