That is "The Hobo’s Method" according to Ilya Pukhalski (source: http://www.smashingmagazine.com/2014/03/05/rethinking-respon... ) and I totally agree with him. That is not efficient way, even lazy way of creating responsive logos. The svg for each logo is repetitive and contains each logo variant - simple sprite technique is used and that is completely not innovative. The same effect could be achieved using png image. Only advantage is that svg saves some space.

It would be much more impressive to see the same parts of logos reused on different variants of logos - "The Man With A Gun’s Method" that is covered in the same article by Ilya Pukhalski.

For comparison: "The Hobo’s Method" - http://responsivelogos.co.uk/images/logo5.svg and "The Man With A Gun’s Method" - http://pukhalski.com/responsive-icons/responsive2.svg

Edit:

It is strange that author publishes (source: http://www.joeharrison.co.uk/projects/responsiveicons ) the information from Smashing Magazine containing the methods of responsive SVG and still uses the poorest method.

I think you've got it backwards. Joe Harrison first published responsiveicons.co.uk and the Smashing Magazine article is a later improvement on it. He didn't use the newer method because it wasn't around when he created the page.

Oh well, that might be the case. My bad.

A logo represents the brand of an entity (more than just abstract iconography), and therefore should not be rearranged and boiled down to elements which are unrecognizable to the brand.

In my view, "The Hobo's Method" is superior in that in keeps in-tact the core identity for each brand. Also, it helps to see real world examples.
