Yes I believe that is the case, dry seals shrink and don't work as well until they expand again. I *think* that was the initial reason my bike puked coolant the first time out after last winter.
If where you store it is never below freezing for extended periods, ie more than a few hours. Theoretically you could keep plain water in the system all through the winter. People come up with elaborate heaters and blankets and ideas to not have to drain the bike.
