It is a smart way, but under windy conditions or otherwise unstable situations, when landing on the support pole, the pin on the support pole has to be locked in place. It is not safe to rely on its weight, only.
This is the same tower as SWG is producing Mojtaba is right Never lower or rise the tower when there is wind But this is with all towers a bad idee , lowering when there is wind
A more broad consideration in designing rigging systems/devices is that a redundancy is required, to prevent substantial failures. All the modes of failure need to be defined and associated risks quantified. This way the allocation of expenditure on redundancies can be optimized.
