4 rakaahs before Asr?

[BADTASTEBEARS]

Assalamualaikum Warahmatullaahi Wabarakaatuh

Ali bin Abu Talib (May Allah be pleased with him)reported: The Prophet (PBUH) used to perform four Rak`ah before the `Asr prayer, separating them with Taslim (i.e., offering blessings) on the favourite angels who are near Allah's proximity and the Muslims and the believers who come after them.
[At-Tirmidhi].

Ibn `Umar (May Allah be pleased with them) reported: The Prophet (PBUH) said, "May Allah have mercy on a man who performs four Rak`ah before the `Asr prayer.''
[Abu Dawud and At-Tirmidhi].

Ali bin Abu Talib (May Allah be pleased with him) reported: The Prophet (PBUH) used to perform two Rak`ah before the `Asr prayer.
[Abu Dawud].

I need clarification. Is this authentic?

we do have 4 rakahs of sunnah before asr but they are not from the sunnah muakkadah which are 12. (2 before fajr, 4 before n 2 after Zuhr, 2 after maghrib and 2 after isha)
