There are two types of movements (move types, not directions) in the problem, and 4 different directions I can move in, my question is not the whole thing but something specific

bool solveRec(int move, vector<vll> &vis, int i, int j, int n, vector<vector<char>> &pth)
{
    if (i == 1 && j == n - 1)
    {
        return true;
    }
    // even move, wherever you want
    if (i < 0 || i > 1 || j >= n || j < 0)
        return false;
    if (vis[i][j] == true)
        return false;
    bool ans = false;
    if (move == 0)
    {

        ans |= solveRec(1, vis, i + 1, j, n, pth);

        ans |= solveRec(1, vis, i - 1, j, n, pth);

        ans |= solveRec(1, vis, i, j + 1, n, pth);

        ans |= solveRec(1, vis, i, j + 1, n, pth);
    }
    else
    {
        if (pth[i][j] == '>')
            ans |= solveRec(0, vis, i, j + 1, n, pth);
        else
            ans |= solveRec(0, vis, i, j - 1, n, pth);
    }

    return ans;
}

When this piece of code :

if (move == 0)
    {

        ans |= solveRec(1, vis, i + 1, j, n, pth);

        ans |= solveRec(1, vis, i - 1, j, n, pth);

        ans |= solveRec(1, vis, i, j + 1, n, pth);

        ans |= solveRec(1, vis, i, j + 1, n, pth);
    }

is changed to :

if (move == 0)
    {
ans = solveRec(1, vis, i + 1, j, n, pth) || solveRec(1, vis, i - 1, j, n, pth) ||
      solveRec(1, vis, i, j + 1, n, pth) || solveRec(1, vis, i + 1, j - 1, n, pth);
    }

to see if moving in any of the directions give a positive (i.e. result in destination to be reached) and if so, ans stores 1 else it stores 0. But earlier while using bitwise OR | nothing happens, but when it is changed to logical OR || the program works as intended. Why is it so?
