1`man exec` is about system call `exec` and its family, not about `.desktop` file. – val - disappointed in SE Apr 30 '18 at 11:58

According to the Desktop Entry Specifications:
%k The location of the desktop file as either a URI (if for example gotten from the vfolder system) or a local filename or empty if no location is known.
What is not obvious from your example at first sight is that sh -c '...' (if that is POSIX /bin/sh and not symlinked to csh) sets positional arguments starting at $0, which means $0 will be whatever is %k.

1No system would be foolish enough to have a sh -> csh symlink. However some old ksh88-based `sh` implementations have been known to put the first argument after the inline script in `$1` instead of `$0`, which is why you sometimes see things like `sh -c 'code "$1"' arg arg` or `sh -c 'shift "$1"; code ${1+"$@"}' 2 1 args...`. Those shouldn't be needed anymore nowadays. Note that `$0` is not a positional argument per se. – Stéphane Chazelas Apr 30 '18 at 09:18
