This is Larry from Brewer's Friend. Correct, the mash steps are for informational purposes.
Everybody has a different process and system (fly sparge, batch sparge, no sparge, RIMS, HERMS, BIAB, etc...). Instead of trying to deal with that in the recipe, the system supports a 'brew' button where you can track your batch progress, calculate efficiency, attenuation, and add journal entries.
The next release will include a mash water management tab on the brew session page where you can track water usage as you brew, calculate infusion temps, etc.
