Yes, yes. I can vouch. I didnt even know mine were a pair until I walked over to the tank to feed one day and saw a clutch of eggs on a leaf. I was shocked! I did see some pre-spawning activity but didn't realize this is what it was and grew concerned that they were suddenly fighting. A few days later, the eggs appeared. The eggs only made it to the wiggler stage (about Day 3) until my Rummynose Tetra made a nice meal of them. As soon as the female saw this, she quickly ate the remaining eggs. As Byron mentioned, if the parents feel any kind of threat toward their eggs/fry, they will eat them before any other fish can.
About 2-3 weeks after the my first spawn, I came home from work to more eggs. There were very few and I quickly realized they had just started to spawn. I quickly grabbed my camera and took a 7 minute video of the female laying the eggs and the male fertilizing them. That is when I learned for sure what the real sexes of each Angel were (You can see my vidoe under the Photography and Videos section called, "VIDEO: Angelfish Actively Spawning. I don't know how to get the link over here). I assumed the one was female from the prior spawn because she was the one protecting the eggs the majority of the time, but this 2nd spawn confirmed it. I actually witnessed the eggs coming out of her papilla. It was quite fascinating and caught that on video as well. The eggs made it all the way through to the free-swimming stage in a community tank. I was amazed. The parents did an amazing job protecting their eggs and fry. They were free-swimming for 2 days until the tetras got a good angle on the fry and started to take them out. The mom must have felt overwhelmed and ate the remaining fry.
Now, about 2 weeks later, I am constantly seeing pre-spawning behavior once again. The female is getting plump again and I believe it is only a matter of time before I see another clutch of eggs.
