I used to shift my old karmann ghia without the clutch all the time, in a similar way. I think if you don't force it, it does no harm. Ulitmately you are getting both shafts in the tranny running at the exact same speed, so they just slide together.
Also, most bike riders I know (except those with HD trannys) shift clutchless all the time.
