The second attempt didn't actually use pdflatex.  Export => PDF doesn't
use pdflatex, it uses latex to create a Postscript file, which is then
converted to PDF.
You can check on the filters used by looking at (checks LyX)
Edit => Preferences and looking at the Converters tab.  That window has
two sub-tabs, Formats and Converters.  The Formats tab defines various
formats (gives them names, says what extension they use etc).
The Converters tab is where the converters between various formats are
defined.  These converters are chained together until you get what you
want.
So, Export => PDF would go in this sequence:
Latex -> DVI (latex)
DVI -> Postscript  (dvips)
Postscript -> PDF (ps2pdf)

Export => PDF (pdflatex) just uses one step:
Latex -> PDF (pdflatex)

And one does get slightly different results depending on which one you
use.  Whether one works better than the other usually depends on the
particular document.
