AS5 on Core2Duo?

I was reading the Arctic Silver website guide on how to apply Arctic Silver 5 on the Core2Duo processors, and it recommends that you apply it in a "line" sort of. I don't understand the purpose of this. Isn't the AS5 supposed to cover the entire top portion of the heatspreader? Why would it matter whether or not you apply it in a line or not? Also, if you followed their instructions and applied it in a line formation, wouldn't you end up putting way too much AS5 on? :(
 
If you apply it the way they say, you use a line but a thin line. Then when you put the HSF on you give it a little twist in either direction. Once the HS is fastened down that thin line spreads out to cover not the whole IHS but mostly the parts of the IHS which are right over the cores and hence the parts where all the heat is.

So yeah, around the edges there will be some metal-on-metal contact, but that doesn't matter much anyway because those aren't hotspots. The important thing is you have a very THIN layer of thermal material between the hot parts of the IHS and the heatsink, which is exactly what you want. If, on the other hand, you tried to apply the AS5 with the goal of coating the whole IHS, the compound would be too thick in the middle where it matters most.

That's a verbose explanation; hope it cleared up any confusion.
