You use part of the extract (I use half the 3lb bag of plain DME) to do the boil,hop additions,etc. Then,take it off the heat at flame out to do the late malt additions. It's already been through a boil,no need to do it again. A small amount is used for better hop utilization.
The remaining heat is enough to sanitize it wit the lid on while you sanitize the FV,etc. Then cool it down to pitch temp in an ice water bath.

Just be sure to account for the difference in hop utilization. Utilization is dependent on the gravity of the boiling wort, so your pre-addition boil will utilize differently than your post-addition boil.

You can use some brewing software to help calculate the differences or check out some hop ultilization charts online. Palmer has a utilization formula in "How to Brew" and Papazian has a few charts in his book as well.
this is currently up for debate on this forum and among the 'scholars' such as Palmer, Jamil, and Papazian. it may have to do with gravity of wort but it may also have nothing to do with that and entirely have to do with boil time to get the hop oil isomerized. check this thread out:
