It’s not a mix of scenarios, but I was trying to emphasize that aircraft’s climb performance might be significantly degraded once memory items are applied (particularly when heavy and with higher flap settings). If you’ve made it to EO acceleration height, then the next segment enables a level flight (or 1.2% climb gradient without acceleration), so at least you’ve got some obstacle clearance in hand before you start reducing thrust and pitch.
Nothing wrong with flying to MSA first, though, but in some places of the world that would take quite a while (MSA in high teens or even higher), even on two engines. Worth mentioning is that EOSIDs can also be flown any time you’ve got a performance issue, they aren’t exclusively there for engine out situations - e.g. with gear that won’t retract when flying an SID with a very high climb gradient required.
