In OALD the entry for might, the second usage is as below:
2 used when showing that something is or was possible
He might say that now (= it is true that he does), but he can soon change his mind.
I have three questions. Please help me clarify.
I don't know whether this example describes his typical trait or a specific occasion where he will probably break his promise but usually he doesn't do it.
Since "might" implies possiblity, why does the note in the bracket say "it is true that he does."? I think it should be "it is likely that he does." instead.
Can I use "but he may/might soon change his mind." in place of "but he can soon change his mind." in this example?
