Correct, but only if such Tagged sections are created.
In the common basic PDF, text exist as a block only so long as there is no deviation from the default linear flow. Any font change (reg to italic, ...) breaks the block and starts a new separate block. Any alteration in the letterspacing/kerning also ends a block and begins another. As a result, what appears to be a paragraph when the document is displayed is actually, at the least, one separate text block for each line and often several blocks per line.
The presence of Tagged text blocks allows readers that are aware of them to skip the fixed layout version of the text, with all its separate pieces, and replace it with the flowable block. With these viewers and with tagged PDFs you have the option to turn on the reflow at the sacrifice of the carefully designed layout.
