Google Translate Mistery

This is funny!

It seems that Google Translate uses prediction as in Google Instant Search but in a strange (and inconsistent) way.

I was looking for the English translation for the Italian "andare d'accordo".

I typed the this: "Andare d'acc" and Google immediately translated into "get along" (see picture below):

Then, once I completed the expression, Google changed its mind and gave a different (wrong) translation:

(Note that "Agree" translates into Italian "essere d'accordo")

I cannot actually explain this strange behavior. Any comment about that is really welcome. :-)
