The mother likely requested the copies of the BCs to get them ready for registration for kindergarten.
Are they long form copies?
Yes. But they are negative copies (like my BC). Don't know why, but some jurisdictions seem to issue negative copies of documents.
These are "photostats." Wiki, though it does show an example of a positive image, says:
Both Rectigraph and Photostat machines consisted of a large camera that photographed documents or papers and exposed an image directly onto rolls of sensitized photographic paper that were about 350 feet (110 m) long. A prism was placed in front of the lens to reverse the image. After a 10-second exposure, the paper was directed to developing and fixing baths, then either air- or machine-dried. The result was a negative print, which took about 2 minutes in total to produce, which could in turn be photographed to make any number of positive prints. [Emphasis added]
