Are they the same? If he (had) escaped...

[36] If he had escaped by jumping out of the window he would have left footprints in the flower-bed beneath. And that is precisely what we found.

I begin by presenting the world in which he jumped out of the window as potentially different from the actual world. But it turns out that the consequential property Q obtains in the real world as well as the imaginary one – and the natural explanation for Q is P, so the inference is that P does in fact hold of the actual world. The strategy here, then, is to reconstruct what happened by working back from consequences to their causes.

Hi. This text is from the Cambridge Grammar of the English Language. Example sentence 36 is cited to demonstrate that a remote conditional can express somebody’s confidence that the if-clause is true.

Question: Can we say “If he escaped by jumping out of the window he would have left footprints in the flower-bed beneath. And that is precisely what we found.” to mean the same thing as the original sentence? (That is, to deduce from the main clause, which is proved to be true, that the if-clause is also true)

Thank you.
