By comparing your remaining stack postflop to the size of the pot, it's a way to gauge the relative value of a hand by explaining how much money you should be comfortable putting in the pot post flop in different situations. It's also a guide to adjust your bet sizing to avoid putting yourself in trouble spots.
So it's a way to mathematically know how much of your stack you should be willing and/or want to get in preflop with different types of hands to make them profitable.
A few examples:
If you have a hand like AA which usually makes one high pair, you want to avoid SPRs near 13 because it sets up spots where opponents can easily bluff you. Of course the lower the SPR the better - getting all in preflop with AA is great.
With suited connectors and pocket pairs, you want very large SPRs so you have good implied odds when you hit, or alternatively, you want SPRs close to 13 so you can bluff your opponents in spots where they have top pair type hands.
It's been a long while since I've read that stuff, so hopefully I accurately represented it.
