Thanks all, who pointed that FullForm of
Infinity is DirectedInfinity[1].
However if I replace _?NumberQ by _?(NumberQ[#]&)
then everything works as expected. This is because
NumberQ[Infinity]-> False.
According to A. Hayes (do You hear Allan?)
recommendation (see How-Why74.nb ) both patterns
should give the same answer. I think this
behaviour is at least misleading.
