The main reasoning for Engagement in the opener that you posted is because it is the faster variant of our opener, an "x-8" opener. There is a limited amount of oGCD space that we have to get all our things on cooldown before using Manafication, and like Kabooa said, Engagement has a shorter animation lock than Displacement. The shorter animation lock allows it to be used with another oGCD without clipping into your GCD and delaying your next GCD.

Starting with corps and displacement first since you're going to use Manafication which will reset their timers first anyways...
I'm not sure where you found this opener, as it is not something that neither me, nor the past RDM mentors at the Balance have ever written. While your reasoning is sound that Manafication resets them, so you want them on cooldown, opening on a fight with abilities off the global cooldown rather than a spell is a huge DPS loss. Your spells are going to be a big chunk of damage, and delaying your spells to get your oGCDs out means you also delay your Manafication and opening melee combo, which would disrupt your rotation for the rest of the fight.
