What is the meaning of the "Temperature" mash step on Brewers Friend?

I found the following recipe on Brewers Friend:

https://www.brewersfriend.com/homebrew/recipe/view/528861/kellermeister



This is a traditional all grain recipe and I would like to brew it with my BIAB setup.

But I'm having trouble understanding/converting the mash steps described on the recipe, which are the following:

Amount Description Type Temp Time

-- Infusion 53 °C 20 min

-- Infusion 65 °C 30 min

-- Temperature 70 °C 30 min

-- Fly Sparge 76 °C 15 min

The Infusion and Sparge steps are quite clear,

But I don't understand what the temperature step means.

What is this step and how does it look in a biab setup?

As indicated by @chthon, it looks like they intend for you to provide external heat to meet the 70 C temperature, not by adding more hot water but by turning on a burner or heat stick.

It is debatable whether these extra steps have much benefit versus an infusion in between, let's say 67 C, for 30+30=60 minutes instead of dividing it up at 30 & 30. But, of course, feel free to experiment and form your own conclusions.

Cheers.

BrewTarget has the same properties for mashing, including infusion and sparge.

In BrewTarget, it means that the temperature is increased by applying external heating.

For BIAB and using a mash setup with a cooler, this is not always feasible, unless an external heat stick is used.

When using a kettle on a direct heat source, it is simpler to increase the temperature of the mash directly.

It could be that the temperature step is just a typo or misconfiguration.
