It probable that if one issues the command then it will be executed even if it snared before actually starting the run.
Unfortunately it isn't the case. Edited for clarity.
Last patch, it was on Crossroads.
Opponent ran over a mine on East near the fuel while trying to chase for a wipe on my squad. I drove my Panther which was being repaired in my base to go and hunt it. By the time my Panther got there the engine damaged T34 had already retreated past the strategic point above the East fuel. It was easily 20+ seconds ago that the T34 had taken the engine damage.
I'm not sure why you haven't encountered it. Perhaps T34-76s aren't popular in team games, or maybe you haven't noticed the bug. Things die a lot faster and there's a lot of activity going on in team games, whereas in 1v1 there's a lot less action so it's super obvious when bugs like these happen.
