Sphinx of the Second Sun will allow to have an additional beginning phase "At the beginning of your postcombat main phase". What does this mean for cards that give additional combat phases? Especially cards like Moraug Fury of Akoum?
Does the "additional combat phase after this phase" line in Moraug Fury of Akoum mean it actually never gets to the "beginning of postcombat main phase"?

505. Main Phase
505.1. There are two main phases in a turn. In each turn, the first main phase (also known as the precombat main phase) and the second main phase (also known as the postcombat main phase) are separated by the combat phase (see rule 506, “Combat Phase”). The precombat and postcombat main phases are individually and collectively known as the main phase.
505.1a Only the first main phase of the turn is a precombat main phase. All other main phases are postcombat main phases. This includes the second main phase of a turn in which the combat phase has been skipped. It is also true of a turn in which an effect has caused an additional combat phase and an additional main phase to be created.

The phase sequence would be one of the following:
Beginning phase
Precombat main phase in which you get a land, triggering Moraug
Additional combat phase (from Moraug)
Combat phase
Postcombat main phase, with Sphinx of the Second Sun triggering at the beginning
Additional beginning phase (from Sphinx of the Second Sun)
Ending phase
Beginning phase
Precombat main phase
Combat phase
Postcombat main phase, with Sphinx of the Second Sun triggering at the beginning, and in which you later get a land, triggering Moraug
Additional combat phase (from Moraug)
Additional beginning phase (from Sphinx of the Second Sun)
Ending phase
Beginning phase
Precombat main phase
Combat phase
Postcombat main phase, with Sphinx of the Second Sun triggering at the beginning, and in which you somehow get a land in response to Sphinx's ability, triggering Moraug
Additional beginning phase (from Sphinx of the Second Sun)
