Not sure, hormones are weird and go all over your body including your brain. Even cis women taking hormonal birth control get more emotional, or cis women in perimenopause/with PCOS on HRT get more emotional. Estrogen really does alter some stuff in your brain chemistry and turn on the emotional granularity button and turn on the crying threshold dial way down.
Trans men on HRT talk about how they lose some ability to differentiate emotions and they get way angrier way faster - also hornier, but whatever.
