Hi.
Please look at sentences (1) and (2).
(1) If it rains tomorrow, the match will be cancelled.
(2) If he was here yesterday, he certainly helped her.
Sentence (1) is a typical conditional sentence in English.
But, it seems to me that the if-clause in sentence (2) is different from the if-clause in sentence (1).
In my view, the if-clause in sentence (2) does not serve as a typical condition.
According to a grammar book of mine, sentence (3) below is given.
(3) It is if it rains...
If he was here yesterday, he certainly helped her
