I'm afraid this explanation needs to be expanded a bit.
High LP on the ISP side for customers' routes is a
common practice, but this makes the perpended AS-PATH

Yes, this is true.
However, if your upstream handles a large portion of the
Internet, that's is a reasonable amount of traffic,
particularly if your secondary ISP is not as well-connected
as the other ISP.
Yep. This consideration implicitly means that an obvious (at the first
glance) idea to buy a broader link from a cheaper and smaller ISP and a
narrower one from a larger and usually more expensive ISP is apparently
wrong. Very frequent mistake enterprise network guys tend to make.
