#3 To give a meaning to last week's angle
Last week on Raw, after Becky Lynch brawled with Ronda Rousey, The Baddest Woman On The Planet asked Stephanie McMahon to reinstate Lynch and put her into the Raw Women's Title Match at WrestleMania 35. After that, Rousey dropped her title and demanded Stephanie to make the right decision.
Now obviously this angle was leading somewhere, and definitely, it did when there was a Twitter beef between Rousey and Lynch, as well as the RAW Women's champion's heel turn that occurred this after she brutally attacked The Man.
Nowadays in WWE, many angles are not clearly explained and the very next week are forgotten.
Such as when Lynch was replaced by Flair to face Rousey at WrestleMania 35, it didn't clearly make sense and WWE did nothing to make it look sensible.
But this angle completely made sense, if Rousey wouldn't have dropped the Raw Women's Title last week, Lynch wouldn't have been reinstated in WWE this week, which would not have made helped in making the attack this week possible.
