It might be related to what I read in $VIMRUNTIME/doc/cmdline.txt
lines 940 sqq. (some lines below the helptag *extension-removal*), as
follows:

Note: Where a file name is expected wildcards expansion is done. On Unix the
shell is used for this, unless it can be done internally (for speed).
Unless in |restricted-mode|, backticks work also, like in >
:n `echo *.c`
But expansion is only done if there are any wildcards before expanding the
'%', '#', etc.. This avoids expanding wildcards inside a file name.
