It is obvious from your screenshot that the formatting is not the same. The paragraph that you are complaining about has been indented by 0.3 cm, probably because you added one or more tabs at the beginning of that paragraph.

Adding tabs immediately in front of the word "venenatis" won't have the same effect because there is a space in front of it. Add the tabs before the space and that paragraph will also indent.

This behaviour is controlled by AutoCorrect. You can change it in File | Options | Proofing | AutoCorrect Options and then deselect the option shown below.
