It also has security clearance implications. Also if he moves back to Finland but remains a US citizen won't the IRS still be able to go after him for tax?

Yes, United States citizens are liable for taxation on their worldwide income (unless there is a tax treaty between the United States and the other country in question).
Only over some threshold (iirc, though it has been some time, around 80k USD equivalent). So maybe yes for someone with a comparatively high income, but not so much a worry for a reasonably large segment of the population. Naturally if this happens to apply to anyone reading I would urge consulting a professional for current advice. ;)
The US has tax treaties with most developed countries, including Finland.
This is highly unlikely, but for instance if you're eligible for a draft, and both countries draft you, one of them is not going to be happy with your response.
There are probably some more likely scenarios where your obligations to one of your nations are in conflict with the other.
