I think the "sections" just include all sentences that use certain keywords to do with that section, and "face" is one of them in this case, as it's part of your body and this is the medical section. But because of that they accidentally also included a sentence that uses "face" in a sense not of a body part but, well, as it's used here.

I'm wondering the same thing

Yes you can, However "en face de" can also mean opposite or facing whereas "devant" only means in front of.
