I brought in the skipFirstHeader flag some years ago. The idea behind is to be able to split a large table in to many pieces, regardless of the size of the page because measuring this size was very slow at that time - to be honest I haven't tested if this has changed nowadays.
What I actually did was to output n lines of a report list of size m using a PdfPTable. After printing these n rows, I created a new table with the same attributes and the same header and started the output of the new table directly after the previous one. This procedure was executed until all m rows had been printed. The problem of this strategy is that the first occurrence of the header line has to get suppressed because otherwise an extra header line will show up between the table segments. Thats why I created the 'skipFirstHeader' solution. It suppresses the output of the first header row to make the table segments look as one big table.
