Some of the effect could be accounted for by a substitution principle; instead of asking oneself for each option whether one’s used it in the last year, it’s easier to ask which of them one recalls using most recently (or just which of them seems most salient to memory), check that, and move on. If people do actually switch between products often enough, this would create that dynamic.
