The main difference is that the original is harder to follow because of shortcomings of the human short-term memory system. You’re still thinking about exactly the same abstract concepts. The potential danger is the lack of exercises, I suspect – that’s where a) first proving things yourself and b) the rederivation habit, come in handy.
I also suspect math students have ample opportunities to crunch through dense thickets of words… why oh why do I suddenly find myself thinking of Munkres’ Topology and Dummit & Foote’s Abstract Algebra?
