How do paragraph-initial gallows effect a paragraph?

[Kaybo]

For one thing, the gallows is not just a 'start of paragraph' marker, in the following sense:

If one simply removes it, then the next character becomes the line initial character, but this character does not have the same distribution as all other line-initial characters.
I can refer to You are not allowed to view links. Register or Login to view. for that aspect.

I have not yet tried to understand this better, but feel that it could be important.

Why should the line start always with the same character? Interesting is that page 58left, were all characters are in the circle containing all variations of the paragraph character, even the weird ones with the additional loops.
