Acerola Supporter card effect
Yes - that is exactly the point.  Sometimes this is just a free heal - sometimes it’s useful to for example play a Tapu Lele or Dedenne another time, or even reuse an ability that was already used that turn (when the Pokémon leaves the zone of play, it no longer is that same Pokémon essentially and can reuse its ability so long as it’s not a ‘only one of X ability can be used per turn’ ability).
Note that if you do this and have no Pokémon on your bench, you lose!
