Carousel still autoplays after first interaction when `data-slide` / `data-bs-slide` omitted

From the documentation, I would assume that a carousel only autoplays if it either has data-bs-ride="true" (autoplays after the first interaction) or data-bs-ride="carousel" (autoplays on load).

When testing this on https://deploy-preview-32638--twbs-bootstrap.netlify.app/docs/5.0/components/carousel/#suppressing-touch-swiping and https://deploy-preview-32639--twbs-bootstrap.netlify.app/docs/4.5/components/carousel/#suppressing-touch-swiping it seems that omitting the data-bs-ride (or data- for 4.5) altogether still ends up behaving like data-bs-ride="true", i.e. after first interaction with the prev or next button, it starts autoplaying anyway (even though the default is, supposedly, false)

Is this...expected?
