When you run OCR on a scanned output, Acrobat analyzes bitmaps of text and substitutes words and characters for those bitmap areas.
If the ideal substitution is uncertain, Acrobat marks the word as suspect. Suspects appear in the PDF as the original bitmap of the word, but the text is included on an invisible layer behind the bitmap of the word. This method makes the word searchable even though it is displayed as a bitmap. Acrobat identifies suspected text errors and displays the image and text side by side in the Secondary toolbar.
