A question about "if clauses"

[Rezafo]

I read below in Oxford English Grammar Course, Micheal Swan & Catherine Walter:

He won't come tomorrow if he came yesterday.

I'd like to hear explanation about this. What type of conditional is it? And, I've never seen "future tense" and "past tense in "if sentence".

Thank you.

 

[Rezafo]

Thank you, but still not clear. What prediction? If the speaker predicted that he didn't come yesterday, then why saying he "won't" come tomorrow. Then will he come? lol

 

[Matthew Wai]

The speaker does not know whether he came yesterday.
The speaker predicts that he won't come tomorrow if he came yesterday.
Whether he will come tomorrow depends on whether he came yesterday.

Don't use quotation marks to emphasize words. Write I've never seen the future tense and a past tense in an "if" sentence. I used quotation marks around if​ because I'm using the word to describe a type of sentence and my own sentence would be unclear without them.

I would use boldface to emphasize words.
