Why is the blitzing play correct in 32S-65R-55 but not in 43S-65R-55?

Comparing the equities, we see that the blitzing play has roughly the same equity in both positions.

However, when we compare the equities after making the 10pt and 11pt, we see that making the 10pt is a much stronger play. A small part if this is because of the two extra pips, but more importantly, White has more numbers that make inner points when he owns his 10pt instead of his 11pt.

By the way, what is the nactation for 20/10 6/1*(2)?
