In Wladimir's example #2 it's clear that the whole b shape was written in a single pass, most probably counter-clockwise. The line thickness as it varies along the glyph suggests that. For other examples, it's not that easy to tell. Вut the fact that im many cases the bottom tip of the apostrophe (or the imaginary continuation of the apostrophe) perfectly joins the tip of the "e" makes one re-think the whole concept.
Wladimir's examples also reinforce the hypothesis that we discussed more than once - that, in Voynichese glyph construction, attachment point matters.
