My Lily 2 will do things like remind me to get up and stretch while I am already moving around cleaning the kitchen or randomly remind me to stop a workout while I am only a few minutes into a workout and my heart rate is fairly high (like 132 today). I used to use the original Lily and did not have either of the issues - the move alert reminders seemed to makes sense - they would happen when sitting still working or sitting still driving. Random reminders to stop a workout a few minutes in with a high heart rate definitely has to be a glitch.
