> VIP PDF is doing the same as Adobe Reader’s Reflow mode, but with a few important differences.

Not so….
Adobe’s “reflow mode” does not use Tagged PDF except in the most minor of ways (within list structures, or so I’ve been told).
VIP PDF uses Tagged PDF.
Accordingly the applications cannot really be compared. The former uses content order, which is fundamentally arbitrary, the latter uses proper logical ordering and semantics.

> The consequence is that PDFs are much more readable in VIP PDF than in Adobe Reader’s Reflow mode.

Yes!
