It has a general look of that some portions of text were missed and awkwardly "inserted" afterwards.
The ot of line 3 was evidently written in the second pass, and I'm not surprised if it was written even after line 1 of the next paragraph was written, because it makes a substantial jump over qokeeody. By the way, one can see a notable difference in tint (and text density!) between first three paragraphs (darker) and the subsequent paragraphs (lighter).
chey teear ykedy ry of line 2 was written after ot.
Next the scribe, still proceeding BTT, comes to filling the rest of line 1, of which the last vord written in the first pass seems to be polaiin. He writes keeey dyaiin, taking a slightly increased space from polaiin to reduce the slope and to make it look more like a coherent line written in a single pass. Next he discovers that he missed the pol, and so he awkwardly fits it into the space between polaiin and keeey. Another possibility is that polkeeey is a single vord, so the line 1 is just filled normally in the BTT fashion. The "pol" part of it is just fit to the left of the lower t, in order for the l in pol not to interfere with the t.
Next comes this "halfline 0" which is awkwardly fit in between gallows of line 1, lest it becomes part of the last line of the preceding paragraph 2. Why would the halfline 0 come in place, to begin with? Maybe the length of the second pass text was such that it could not be fit into three lines? However, there is free space in line 3 yet. All in all, looks like some miscalculation or omission.
