Putting the two sentences here together suggests, to me, that your balance will fall when the payments cease to be 'pending':

i.e. if "payments will reflect on your PayPal Credit account the same day you make them" but "it may take a few days for your available balance to update", I can't see how that could happen unless payments are shown as 'pending' up until the time that your available balance has been reduced.
