PlayerMoveEvent getTo() method not working properly?

Before I give any text, here's the code in question:

Code:

@EventHandler
    public void onPlayerMove(PlayerMoveEvent event) {
        Player player = event.getPlayer();
        Location loc = event.getTo();
        if (loc.getBlock().getType() != Material.SPONGE) {
            player.sendMessage("notsponge");
            return;
        }

I'm just asking if event.getTo() returns the block the player is now standing on, or the new location of the player's top half or something. Basically, whenever I'm standing on sponge I'll get the "notsponge" message when I move around on it, and my code seems alright, so my only conclusion is that event.getTo() does not give the block the player moved to.

It's the block inside the feet. You have to check below the player using Block#getRelative
