Soft returns and hard returns when pasting

Following up on question, if I copy a fallacy description with its title from this website, and paste into Logseq, I get one block with soft returns between lines. If I copy and paste a fallacy description without its title (copying just the text under the title) and paste into Logseq, I get a new block with each new line. Something about including the title of the fallacy in the copy triggers Logseq to receive the pasted copy as a single block. Does anyone have knowledge about this? I would like to choose whether multi-line text is pasted into Logseq as one block, or multiple blocks tracking each line break. Cmd + Shft + V seems to force only the latter option. But I can’t seem to choose the first option, unless as in this case, the name of the fallacy is included in the paste.
