Why the "?P a rdf:Property" test?  ?P can only be a property can't it?

Why isn't this:

[] q:select {"1234" ?P ?O. ?O ?Q ?X}
   q:where {"1234" ?P ?O. ?O ?Q ?X}

I don't understand how this one works.  Is it doing an optional :email?  If
so, how? I don'tunderstand the interaction of two q:select statements I
guess.
