Probably yeah, I believe Strava ignores the 'auto-paused' time and only stops the clock when the GPS thinks you've actually stopped. So that time you cruise up to a red light at 1.5mph is counted by Strava but not Garmin (assuming you have auto-pause on). For this reason Strava always thinks my rides are slightly longer and slower than Garmin (at least that's my excuse!)..
