Crape Myrtle is a broad name for an extensive group of plants. There a more than fifty named varieties of Crape Myrtle and they range in mature height of 10 feet to 30 feet plus.

Crape Murder is the current buzzword for what people have decided is improper pruning. The crape myrtle will respond to what you do to it. Fortunately, they are hard to kill. They are however easy to mess up with improper pruning.

Ours was put in by the builder so I do not know for sure what variety it is. The plant structure is small tree like-two major trunks. It is currently about 20 feet high. It would never be the multi stemmed plant in the OP.
