Ever since Sun and Moon, a feature was introduced in that certain species of Pokémon try to learn a new Move automatically as soon as they evolve; this is colloquially known as "Evolve Move".

If a Pokémon evolves, say, well after the Level it would have normally evolved, it's possible for the evolved stage to try to learn multiple Moves at once in that both the Evolve Move and the Move it normally would learn at that Level come up "at the same time"; in this specific instance, the Level Up Move takes precedence over the Evolve Move.
For example, an Ivysaur that evolves into Venusaur at Level 51 will try to learn Double-Edge first, as Venusaur learns Double-Edge at Level 51, and then Petal Blizzard, Venusaur's Evolve Move.
