The gallows intrusion, the baseline jumps and multipass

[Anton]

I find it more compelling to think that, writers being sloppy and pages being unruled, this is a case of fitting the gallows to the above word, which happened to be slightly high by sloppy accident. 

How about baseline jumps within vords themselves?

In fact, many vords starting with o followed by gallows have their baseline jump up starting from the said gallows.
