PreviewText
StripHtml was probably not a good method name for this one as it does much more than strip away html, it was built for search results and have a algorithm that tries to extract the beginning of some sentences. The length property will control how much html that is being processed rather than the actual text being returned to you.
Another html strip method (see CreatePreviewText) is used by the subscription mailer, a sample can be found at:

I've never used the TextIndexer.StripHtml instead I've made my own stipper.

using System.Text.RegularExpressions;
public string StripHTML(string text, int maxlen)
{
string output;
output = Regex.Replace(text, "<[^>]*>", " ");
if (output.Length > maxlen)
return output.Substring(0, maxlen) + "...";
else
return output;
}

As Per mentioned, the PreviewText does not work the way it is described in the SDK. This has been corrected in the next version of the SDK. The correct description below:
PageTemplateContainer.PreviewText:
The preview text is determined by the following: If the page has a MainIntro property, this string is used to create the preview text, otherwise the MainBody property is used, if it exists. The first 400 characters of the text is extracted and cleaned from any html. Finally, the remaining text is split into truncated sentences using the format "First truncated sentence... Second truncated sentence... etc". If the page has neither a MainIntro nor a MainBody property, an empty string is returned.
