I believe you're right, and I read in Fathul Bari that the two mountains mentioned in the Hadeeth are Makkah mountains and Ibn Hajar named them : one is called (Abu-Qubais) and the other is either (Qua'iqia'an) or (Aljabal Alahmar i.e The Red Mountain).
and Allah knows best.
jazakum Allah Khairan for the new fa'idah.
