Perfectly acceptable. Re-using it that quickly after you harvested it means you don't even need to make a starter. If it was a week or two later, I would then make a starter.
Tip: You can take that yeast cake from the fermenter, pour it into a large container, shake, then wait 20 minutes...pour off just the top-most liquid and split it into 4 containers. Each one represents enough yeast for a batch, generally.
