My understanding is fuzzy, but the sense I get is that the word "when" just attaches to the possible configurations rather than being a condition. A rephrasing of the idea might be:

"Multiply by 1 for the configuration in which the photon goes straight, and multiply by i for the configuration in which the photon turns at a right angle."

Which results in two configurations every time, rather than different configurations depending on what the photon does.

'I think the problem some of us are having is reading "They would send a photon toward the half-silvered mirror ..." precludes the possibility of there being two results. I didn't think to not picture a little (billiard) ball being propelled towards a "half-silvered mirror" and it ending up at one (and only one) of the detectors.
