They do. If you listen to the way the ref announced it, he said the illegal forward pass wasn't a "simple foul". Meaning the if it had been an illegal formation or something along those lines, they would have enforced both penalties and the Bears would have gotten 10 yards. I do, however, have a problem with their definition of a simple foul. Anything that only results in a 5 yard penalty, loss of down or not, should not offset a pretty brutal personal foul call.
