vertices values and n transform

i put an object in top view and look at the values of the vertices in the n transform panel

the object is placed on the right of y axis top view
so all x values shouldbe postiives but almost 1/2 of them are negatives
Found something else i was in local mode !!!
but i alos did an experiment with a script and i get the lcoal mode also
with negative number
is threre a way to read the global values instead with the script?

is it possible to reset as per the location of teh object ?
using the Ctrl-A does not change the location values!

Thanks
