The Google algo changes often so it is hardly possible to get a definitive answer to this question.
However, Google usually encourage the good style and may filter out the spam suspicious deviations.
In general good style means one page per one topic. It means also one H1 tag per page.

If we understand what W3 has to say about the use of H1, then perhaps the best thing would be to be a bit objective about what might happen if you decided to use more than one H1 on a page...
According to W3, the H1 heading is supposed to be reserved for the most important level. So if you were to use more than one H1 (let's say two), then objectively we can say Google might treat the two headings as equals. If you were to use four H1 on a page, then all four would be equal.
These elements are supposed to create a hierarchy on the page. Use of multiple H1 elements, therefore creates a rather flat hierarchy (if that's possible). That might make it difficult for Google to figure out what the page is really all about and result in possibly lower ranking.
In practice, I reserve this element for the single most important heading on a page. I limit myself to one H1 element on each page.
700th post - cool.
Think of it this way, the document contains an implicit <h0> value that contains everything else.
Having said that, I doubt search engines bother to analyse heading structures - it would be a totally pointless waste of CPU power.

So Kaled votes that heading elements are not used in the algo at all. That's an opinion based on programming knowlege. For me, I still vote to use the structure as W3 outlines. Which I also think is easier on the reader.

Just for the record, search engines strive to produce relevant results - this may come as a shock to some people but relevancy is not determined by page structure. A beautifully structured page with rubbish content does not deserve to rank higher than than a poorly structured page with good content. However, it seems many webmasters hope that structure is important - presumably because their content isn't good enough.
