I just used the original headline from the blog. You're correct that it makes sense in context, but that is why the "recording your moves" part is in quotes. It's a direct quote from the O'Reilly headline.

Anyway the larger issue is that it is not clear exactly what information is being logged. We know some location info is vulnerable, but exactly what and how much? The O'Reilly researchers really should have done a better job. The least they should have done was to run some controlled experiments with a freshly wiped phone.
