First I'd like to thank the author for taking the time and risk to put this article together.
Now, one thing that may be occurring here is in fact Apple's latest firmware. The fans are designed to kick in to high-gear when the notebook acheives a certain temperature. So, whether you've re-applied your thermal paste or not, the MacBook Pro will still try to keep the system within a certain temperature range.
IF this is indeed the case, then you will likely not notice much of a temperature difference after re-application, but may instead notice a difference in when the fans kick-in and in how long the fans run to bring the machine back to target temperatures.
The only other suggestion I can make is to always get a baseline temperature reading (and fan-timing as noted above) before re-applying to get an accurate picture of any changes that may have occurred. It could be that the authors neighbor had a MacBook with a better application of thermal paste than his own model to begin with.
