Its a phenomenon that is visible on such graphs but its not that impressive and there are actually multiple causes.
Although some of the death reductions are caused by people that would have lived till then having died earlier because of the pandemic, there are other factors. Such as the effects of lockdown and reduced economic activity, equivalent to start of a recession that would be expected to reduce deaths due to factors such as air pollution, and people not going out and indulging in risky behaviour. And the effects of lockdowns and other measures reducing the number of other illnesses at various times.
And certainly the level that deaths fell to after the first wave was not an indicator of their future potential to rise, it didnt stop deaths reaching horrible levels again when the second wave came along.
Although a large number of vulnerable people lost their lives already in this pandemic, I dont think the overall state of the nations health is positively transformed as a result. Especially not with the healthcare backlog that has accumulated so far, and the currently unknown scale and longer term impact of things like long Covid, state of health and care services etc.
Anyway here is an updated graph which shows the period I hadnt filled in on the graph I posted the other day. It shows deaths from all causes per day for England only. Deaths have been especially low again recently, but I expect those figure to bounce back at some point. I dont know exactly what the baseline they've used is based on but it does provide a guide as to how much deaths are expected to change with the seasons in normal, non-pandemic times.
