I knew something didn't smell right. Need to call some friends tomorrow. Errr... I mean later today.
Hopefully it is as Oz noted and a couple of kids just being kids and the two affecting each other. As late as these two commitments were in the process maybe things were about the pressure of the process for both sides. Something like the enthusiasm of an old time altar call. It does put PSU in the awkward position of having only one commitment for 2012, a class of one recruit and one transfer in 2011.
Both situations do say that Penn State does remain in the hunt. So that sounds unlike anything too big.
