I beleive they are the same incident, and that 04L was mistakenly reported as the runway being involved.
I read elsewhere where the 747 on 04R is in the new arrestor barrier section they installed to keep aircraft from going off the end and into the water. That pavement in this section pretty much breaks up under the aircraft's own weight, so extracating it is more involved than just towing it off, not to mention there being a foot of snow on the ground. Monday might be Tuesday...
Here's what the arrestor bed looks like, and how it saved a Saab 340 from the water back 1999. You can see than even wheels of a lightweight Saab are not -on- the pavement, but -in- it, so you can imagine what a heavyweight 747 must look like in it.
A MD11 did use it in 2003, but he didn't go very far into it, and only the nosewheel was buried.
Here's some of the airports around the USA that have such installations:
