Edit vs open from command line

I have two classes, Sub and Super, where Sub is a subclass of Super. Both m-files are in the same folder (say /path/to/mydir). I noticed a difference between using open and edit from the command line. If the current directory is /path/to/mydir, then using either

edit Sub.m
open Sub.m

open Sub.m in the editor. However, if the current directory is a different one and /path/to/mydir is on the Path, then

edit Sub.m

opens Super.m, while

open Sub.m

opens Sub.m in the editor. What is the difference between using edit or open for m-files?

If it's relevant, I'm using MATLAB R2014b on Linux.

That's odd that edit Sub.m would open Super.m. Perhaps

which('Sub.m','-all')

could help trace the problem?

Using which with the -all option shows the correct Sub.m and nothing else.

I'm not sure if that is relevant but these files are in an SVN repository and I had used svn cp to get them into the current branch from another branch.

This problem of edit opening the wrong file does not occur for other subclass/superclass combinations which were either created inside this folder or copied into it using the regular Linux cp command .
