I play drums. This is not a reasonable concern.

You won’t skill up in terms of being able to play a drum kit with this pad thing, but it will get you used to keeping time and learning how to separate your limbs (like how you slowly are able to tap a different pattern with your right foot than you are doing with your right hand).

if you’re worried about it, cross your right hand over your left and keep rhythm on the hi-hats with your right while hitting the accents with your left.
