Does 'coming from ' necessarily refer to the speaker?

Question

If I were to say something like "That's false, coming from someone who has lived in China for 3 years", then does the 'someone' in the sentence necessarily refer to myself?

Answer 1

"Coming from someone..." does not necessarily have to refer to the speaker (first person) Although, it is always singular. Consider:

"I understand why that would seem valid, coming from someone with a mother like yours." (Second person)

"Fashion critiques are hard to take seriously, coming from someone who dresses like Zelda." (Third person)
