No, a keyfile is processed the same way as passphrases.
But your previous passphrase (keyslot 0) used less memory.

With PBKDF2, the memory footprint is even smaller, just a few kilobytes.

It is only about probability & luck - passphrase could fail the same way.
Argon2 KDF is just a quite good memory pressure test :)
