I think this is the expected behavior. When you export to latex, in order
to ensure compilation, all images gets converted to a format that latex
understands. If you reference a svg image and export to pdflatex, this
image has to be converted. On the other hand, if you reference a png image
no conversion is needed, because pdflatex can deal with pngs.
Note that it means nothing that you saved elsewhere the document, because
full paths are still used to point to the original images (that are not
moved alongside the document, or that are always found in the lyx installation
directory for the icon info inset). Also note that the icon info inset is
simply equivalent to the graphics inset.
This is nothing new, I think, and you should have got the same result if
you tried exporting to plain latex in the case of png icons, because in
this case all pngs should be converted to postscript. However, nobody
seems producing dvi or postscript output for the lyx documentation and
thus this was going unnoticed when the icons were in png format.
This only occurs if you first export to latex, but of course you can always
produce output directly from lyx, because in this case all images are
copied to the temporary directory.
In conclusion, if your document references an image located in a directory
where you have no writing rights, you cannot export your document to latex
without incurring in those shortcomings. Nothing new.

Of course, this is also expected.
