Chinese ancestry in Indonesia is extremely reduced. Chinese Han have about 25% y-dna O3a3c (M134), but Indonesians have only 0.25%, so the maximum possible recent ancestry from China is 1%.

R1b1* and R1b1b1 are present at very low rates in Chinese Han, because they have only 0.5% y-dna R, and most of that is clearly R1a.

So there are at most just 20 Chinese origin samples amongst the 2,000 Indonesian samples in the study. R1b1* plus R1b1b1 make up less than 0.2% of Chinese y-dna. Ergo, the likelihood of finding 2 samples of R1b1(xR1b1b2) is less than 1 in 600. And that's using the generous estimate of 0.2% R1b1(xR1b1b2) in China; I didn't find a single sample of R1b1b1 with 390=19 out of 5,000 Chinese samples in yhrd, and the 390=19 cluster is the biggest cluster of R1b1b1.
