That is true and it might further be impossible to do itat all.
GnuPG has a feature to suppress the key ID in the mesage and it has
therefore to try each secret key in turn until it finds a suitable
one.

There are 3 ways to figure out the the key to be used:

 a) Do not provide a passphrase and gpg will tell you which
    key is needed.  Then run it again with the correct passphrase.
    This is not bulletproof.
    
 b) Use --command-fd and look out for a passphrase request.  Consult
    gpgme on how to do this.
    
 c) Don't care about this at all and let gpg-agent handle it.

Because gpg-agent is not yet available for Windows and is still
quite new, b) is the preferred method to pass the passphrase.
