Maybe because DeinflectReason.Tari was repeated twice on line 179 and 180, whereas it usually looks like it's alternating between DeinflectReason.Tara and DeinflectReason.Tari?
Anyway, not clear if this is on purpose or not. If it's a bug, I can create a PR to fix it if you like.
I was recently updating some inflection data for https://github.com/FooSoft/yomichan/pull/199 and it was noticed that there are some rules which seem to be mixed up. Specifically, some of the -tari and -tara rules seem to be switched. For example, see 往ったら on lines 178 and 182 of: https://github.com/birtles/rikaichamp/blob/1467cf459c974b86889a39993ce469aa289f2ea2/src/deinflect.ts#L178-L182
