Consider “Zayd and Amr are courageous like lions.” There are two subjects, a shared comparison term, and an expressly named respect—courage. This is therefore both taswiya and detailed (mufaṣṣal).
Now consider “Zayd is like a lion and a mountain.” If lion suggests courage and mountain suggests stability as separate resemblances, there is one subject with two comparison terms: jamʿ. If the relevant respects are not explicitly stated, it may also be condensed (mujmal).
Separately determining the terms and their number, the nature of the respect, and whether that respect was expressed or omitted yields a more reliable analysis.
