This behavior is actually perfectly normal whether NFS is used or not.

It is simply a consequence of the editor you use, here the legacy BSD vi, not doing any concurrent edition avoidance.

Should you have used vim, the editor would have prevented or at least warned you about the situation regardless of whether the file system is local or remote, and supports file locking or not. vim tries to create a temporary file (.swp) when you open a file in read/write mode. Should this file already exists, it ask you about the issue and wait for your decision.

NAME
evim - easy Vim, edit a file with Vim and setup for modeless editing SYNOPSIS
evim [options] [file ..] eview DESCRIPTION
eVim starts Vim and sets options to make it behave like a modeless editor. This is still Vim but used as a point-and-click editor. This feels a lot like using Notepad on MS-Windows. eVim will always run in the GUI, to enable the use of menus and toolbar. Only to be used for people who really can't work with Vim in the normal way. Editing will be much less efficient. eview is the same, but starts in read-only mode. It works just like evim -R. See vim(1) for details about Vim, options, etc. The 'insertmode' option is set to be able to type text directly. Mappings are setup to make Copy and Paste work with the MS-Windows keys. CTRL-X cuts text, CTRL-C copies text and CTRL-V pastes text. Use CTRL-Q to obtain the original meaning of CTRL-V. OPTIONS
See vim(1). FILES
/usr/share/vim/vim62/evim.vim The script loaded to initialize eVim. AKA
Also Known As "Vim for gumbies". When using evim you are expected to take a handkerchief, make a knot in each corner and wear it on your head. SEE ALSO
