quoting out of context...and poor reading comprehension
As noted by Alfven, this "concept" was just a mathematical approach to treating plasmas, and as also noted it worked, but did not accurately represent the actual process. In this way it was like Ptolemy's epicycles, or the "curved space" contrivance of relativists. The method also produced the right answer, but for "wrong" reasons.
The concept of "magnetic field lines" is a contrivance. These "field lines" are not real, but an imaginary construct. They can not "break" and "reconnect". For this reason, that approach to dealing with plasmas is just as specious as "frozen in" magnetic fields, or ptolemic epicycles. It's a mathematical contrivance that gives the right answer, but does not in any way reflect the reality of the situation. This is actually pretty common when researchers delve wholly into abstract math and never perform experiments to verify their claims.
He did not say his "previous approach" (early tool) was pseudoscience, he said it was pseudopedagogical, which means it's not a suitable teaching method because it does not satisfactorily explain the underlying phenomenon (though it does give the "right" answer). Alfven's mistake was concluding that because it gave the right answer that it may actually illuminate the process itself. The method was developed as a contrivance, an abstract tool for calculating an answer, not as a hypothesis to explain the phenomenon, which should be clear from Alfven's own words that you quoted.
And so on. Alfvén is apologizing for his role in promoting the frozen-in concept

and the non-Maxwellian concept of magnetic field lines that goes with it.

Ironic, isn't it? In attempting to undo the damage he had done to his field, Alfvén condemned the results of his own previous approach as pseudoscience

Who has quoted these words, where? I think you're dangerously close to setting up a straw men here.writing words that Michael Mozina and other hobbyists would later interpret as a condemnation of the legitimate Maxwellian concepts of magnetic field lines and magnetic reconnection.
