Mag'har Orcs did not join the Horde until BfA. The only hamfisted explanation there could possibly be, is that she ventured to Azeroth as soon as the portals were opened, instantly travelled to Pandaria, and immediately enrolled in a Pandaren temple to be trained by a master in the ways of the monk. Even then, it is highly dubious that she could have attained her powers in the limited timespan between WoD and BfA. One of her abilities is to summon spirits of Xuen, which is a very high-level Windwalker ability reserved for only the most powerful, well-attuned of students. Another of her abilities is to transform into an avatar of the Jade Serpent herself, one of the most coveted Mistweaver abilities. There is, quite simply, not nearly enough time for her to have trained in both the ways of Xuen and Yu'lon in the limited timeframe between the start of WoD and the Battle of Dazar'alor; let alone having mastered both of these paths that take decades of training to grow proficient in.

Even more proof this Orc is a liar, as all outsiders are. Your day of reckoning will come, as will mine. Whether she is lying about being a Mag'har Orc (maybe painting her skin brown? wtf Blizzard?), or she is an undercover member of the Infinite Dragonflight, or she's a Dreadlord in disguise. That is the only way her story makes sense.
