Don't the FAA rules in question refer only to training by an unqualified (i.e. not instrument rated) pilot?
Surely if a "real" ILS is flown by a suitably quailified pilot for recovery to base or another airfield for the purposes of landing then by definition it's not a practice ILS at all.
If by "real" you mean conducted in actual instrument conditions, then yes, it would count toward currency requirements. Otherwise, no.
