I can't really answer you on the does it matter part, but I can help you
with the cutting part.
First you have to account for the part of the glass that does NOT extend
into the channel. Only an 1/8" to 3/16" of an inch go into the channel
(depending on the size of the channel), so you have to "add" the extra
length needed to make it to the "zinc" end, not the glass end.
The best way to do this is to cut your first 45. Then lay it aside of
the panel and see where the glass ends and put a mark on the side of the
zinc. Then measure (or judge) how far into the zinc the glass will go.
At that intersection of your lines is where the 45 line must fall. move
to the right and it's too small, to the left and it's too big. ( or
Morton's clean cut is also a handy tool for cutting zinc channel (or
copper, brass) . It allows you to use any commercial hack saw or
jewelers saw. It is easy and compact to hold and use unlike a larger
commercial mitre box.
Hope this helps
