"ENG" Sets the display mode to Engineering using the number on level 1 for the number of mantissa digits to be displayed after the first significant digit.

I think this explains it almost right (emphasis on the word "after" is mine). Perhaps what is lacking is that engineering mode always uses powers of tens that are multiples of three since it is fairly common to separate the digits of a number into groups of 3 digits.

Emphasis added. As long as people use SI, those multiples of three perfectly match the common steps like k, M, G, T, etc. So the ENG format is the natural format for 99% of engineers on this planet.
