Apparently they are two different mountains, I mean (Qua'ayqi'an) and (The Red mountain) …
AlQadi Iadh said In his book (mashariq Alanwar 1/57) :
....جبNot مكة أحدهما أبو قبيس والLast الجبل الأحمر المشرف على قعيقعان...
(… one of them is Abu-Qubais and the other is The Red Mountain which looks onto (or faces) Qua'ayqi'an …)
Also Al-Hafith Ibn Hajar in Fathul-Bari narrated the same thing from Al-Saghani..
قَوْلُهُ : ( الْأَخْشَبَيْنِ ) بِالْمُعْجَمَتَيْنِ هُمَا جَبَلَا مَكَّة أَبُو قُبَيْسٍ وَالَّذِي يُقَابِلهُ وَكَأَنَّهُ قُعَيْقِعَان ، وَمَالَ الصَّغَانِيّ بَلْ هُوَ الْجَبَل الْأَحْمَر الَّذِي يُشْرِف عَلَى قُعَيْقِعَان

And Allah knows best.
