It's the same.
Just that most people use the first index for players, because every player has 10 TextDraws (in your case).
But it's totally legit the other way round, it's just depending on how you prefer it.
However there are situations, where the order is very important. In the first version you can assign all 10 textdraw IDs at once (not sure why you would do that, thats why it doesn't matter for your example).
But:
PHP код:
new A[4] = {1, 3, 2, 5};
new B[10][4];
// Later you can do:
B[3] = A;
// Doesn't work on this:
new C[4][10];
