Depending on the explosive that should not help. Shaped charges are most effective if they explode a little distance away. It might help if it is a shrapnel based explosive.
Still you wouldn’t probably need a shaped charge to penetrate the armor on a BMP-2 which may explain this approach.
Edit: looking at it more, there is some kind of external armor assembly on the sides, but it doesn’t look like ERA tiles.
