Likely, this is a standard term in their inventor assignment contract. When bsenftner signed it, the patent applications were probably not public yet (there is an 18 month period between filing and publication in which the application remains "secret"), and during that period it makes sense to have a non-disclosure term.

As for the current owner being a front... if it is, it's not a very good one (real patent troll companies are much better at it, using shell corporations in various jurisdictions, each tied to a single or a small number of patent families).
