Some people might see a load of emotional advice, support groups, maybe a clinic.
Someone else might see a load of religous advice, pro-life groups, maybe a church.
Let's look at your fictional example.
If my page got a #1 for Abortion and it dealt with emotional advice and it turned up #1 for someone searching for legal advice, it would get a high bounce rate.
What you are missing, RegDCP is that you are looking at a query in isolation.
Your page may not turn up as #1 to someone searching legal advice. Google will make a decision based on past searches and their intent. So if past searches were to do with legal advice, then #1 may not be your page with emotional advice.
On the other hand, if your page is covering both, the legal and emotional issues and is strong in its #1 position, then it may still show as #1.
The thing is - you never know for sure.
I am using a tracking tool that for every hit shows me a page the user landed to, the query and the full referer URL. On many occassions it also shows the position the page was in Google SERPs. On many occasssions when I enter this exact referer from Google SERPs, I am not seeing the page on position the tracking tool said it was. Sometimes the page is not even in the first few pages of SERPs for the query, yet it was there for the visitor. On other occassions it is exactly where the refering query said it was. For selected queries I was following this closely and what I can say is that there are no rules.
You can also see this if you learn to read Queries from WMT, filtering it down to a country and "web" and then drilling down at the query details which shows you which page ranked and in what position.
