@sivan_yair and I read this today and had a question — what are the admixture proportions behind fig 4? Does this effect of shorter tract lengths for stronger selection (conditioning on present-day allele frequency) depend on staying for a long time below the drift-barrier freq? pic.twitter.com/COrXg9FCBU

That is perhaps one way to look at it. Conditional on a high current frequency and an old introgression event, the paths with highest probabilities are paths where the increase in allele frequency is recent. 1/2

With a recent increase there is less chance of back-recombination to the introgressed haplotype background. Hence, the tracts will be shorter. 2/2
