Implied open condition + would have?

The letter may be the sort of crazed correspondence attracted by politicians, except for the fact that Stalin, who did not keep much in his personal archive, filed the letter. The mention of his mother rings true, for Keke surely would have helped her beloved Soso in a situation that can hardly have been unknown among the young Casanovas of Georgia.

Context: A woman wrote to Stalin about her niece, Pasha, who was allegedly fathered by Stalin himself in 1899. The letter claims that Stalin’s mother had taken an interest in the child, Pasha, who herself remembered Keke (Stalin's mother). Soso is Stalin. Excerpt From: Simon Sebag Montefiore. “Young Stalin.”

Hi, dear teachers. Does the "would have helped" imply an open condition: If Stalin was in that situation? Thank you very much.
