I genuinely don't know, and I've puzzled over that one for a LONG time.
To begin with, Identify as a whole is one of the most FUBAR spells in all of 1e; seriously, it's like Gygax finished it, and was like... naw, let's make it even MOAR GYGAX.
It's got everything.
Dense, nearly impenetrable verbiage? Check!
Does it take forever and then some to cast? You betcha! (ONE TURN!)
Does it have a labyrinthine number of conditions? I can't even count them all!
Does casting this first level spell lead to terrible things happening, up to and including the death of the caster? YOU DON'T SAY!
Does it have the possibility of destroying the object that you actually want to identify? Why not????
Do you need to spend a ton of money just to cast this useless spell? SURE!
Heck, let's just humiliate the caster by making them do some gross stuff with material components, too! THUS SPAKETH THE GYGAX.
For the record-
The material components of this spell are a pearl (of at least 100 g.p. value) and an owl feather steeped in wine, with the infusion drunk and a live miniature carp swallowed whole prior to spell casting.
So, here's what I've got. Owls are wise. Okay.
The pearl in wine bit? That's from Cleopatra. Sure.
Miniature carp? Eh .... got me.
