Google will be consolidating monthly updates into quarterly update not long from now. Unless a vulnerability is high, then those get addressed ASAP. I am not saying that these monthly updates happening later and later in the month where they are used brings up questions, just that people will be asking lots of questions when none is seen after the month passes.
On Samsung devices this can take a bit longer in the west like here in the US. Samsung has its own security platform in its built-in firmware aka Knox. So Samsung updates both the google updates with its in-house Knox platform into one security update. Then it releases them to the carriers for their own adjustments.
Anyway, Google has already been doing starting in July and was made the news over two months ago.
