Ok I didn't know some shells do it (interpret literal ~ in PATH), but
other shells don't.
This turns out to be shell-dependent thing:

Shell Interprets literal~ in PATH ?
------- -----------------
bash yes
tcsh no
csh no
ksh no
zsh no
dash no (posix-compatible shell)
ash no (another posix-compatibl shell)
------- -----------------

If you insist on having literal ~ in your $PATH,
then adding this line to ~/.vimrc
will fix results of executable():

let $PATH=substitute($PATH,'\~',$HOME,'g')
