Probably normal, although if it seems dramatically different from other bikes you've owned, then this is odd as it appears more/less the same to me. If the other bikes you've owned have had cable clutches rather than hydraulic, that's probably the reason as a hydraulic clutch lever tends not to have much (if any) "free play" like a cable clutch lever.
The actual displacement distance of the lever to the point the clutch disengages is not the key thing - it's whether it starts disengaging as you start to apply lever pressure. It's normal for a clutch to start slipping right at the point where you're starting to notice that you're putting non-trivial pressure on the lever - they're calibrated this way to have the lightest clutch pull that still has enough spring pressure for full engagement with no pressure on the lever.
