Issue with Point Labeling

I have created labels for visible drafting points in a view by getting the 3D point object names. After a while i update the point names in 3D and when i recreate the labels for the same views, i am not getting the updated names from 3D. I tried creating a new view and labeled the points using the macro.(This way i am getting the updated names)

1>Is this a inherent nature of the drafting views..?? or
2>Is this something wrong with my journal...

i have posted the journal in the below link
