Although your question wasn't for me, I do have a cam mounted to the top of the dashboard for the following reasons:
1. Virtually no reflections which considerably improves video quality.
2. In my car, with the large plastic sensor housing for the auto-lights and auto-wipers, and with wiper blades covering almost the whole windscreen, it's difficult to mount most cams in a legal position (and ironically those which are technically legal tend to interfere more with my field of view!). See picture below.
3. Some cams have more versatile mounts, some can have their image inverted, and some can do both, which makes dash-top mounting of those cams easier.
But it has a few potential downsides:
1. Positioned in full sun, so could get very hot (although my dash-top cam is silver in colour so reflects a lot of the light, including it causing a bit more windscreen reflection).
2. More visible to a thief (although my car, being a DPF-equipped diesel, tends not to be used much in town or car parks; I use our small petrol car for that).
3. At night, headlamps of oncoming cars shine straight into the camera, which isn't the case with a high-mounted camera.
4. When it's wet, reflections off puddles, especially at night, also affect image quality.
