When the function is a predicate, t/nil makes more sense (generally speaking, there are exceptions) that non-nil/nil. In this and the other patches, I've opted for the fix (either doc fix, or code fix) that I thought it was more logical, or matched better the function's intent, or less prone to cause a bug.
