That's largely it -- tropical convection results from a nearly moist profile and has a natural resilience to downdrafts. But, bring in some dry air in the mid-levels and you create conditions favorable for strong evaporative cooling as well as the development of downdrafts. Downdrafts can help develop convection elsewhere, but more specifically they mark the collapse of the pre-existing convection. That's not good for a tropical cyclone.
