I think it could be ambiguous in certain situations. Let's say I wanted to conditionally set a variable to one of two negative constants. In the current syntax, that would look like:
x = -1 if y else -2
However, with your syntax, it would look like:
x = if y -1 else -2
Which could be possibly confused with trying to subtract 1 from y.
It's been a while since I've read it, but I believe it's partially a reference to a lute song called "Flow my tears" [1], but it's also a reference to a moment near the end of the book when one of the policemen has an embrace with a man he just met at a gas station following the death of the policeman's sister.
