The YBM Instant has long existed to reward booking a costly fare (perhaps greater then first class) and provide a route to first class for those not permitted by employer policy to purchase first class.

Recently UA "cheaper" B fares in conjunction with a bundled E+ access and for a continuing PremPlus ticket segment without PremPlus seating.
In the PremPlus cases there did seem to be a logic for the B to provide first class access for higher elites.

However, It was offered to non-elites as a way to get E+ (and therefore no fear of them making use of Instant Upgrade) BUT elites found if you force B you got a cheapo B fare and could upgrade it. But the Bundled E+ B fare made no sense for higher elites as those elites already had E+ access, and now they had the discount B they could upgrade, contrary to the original intent.
Why UA used B fare class, I do not understand but it was a mistake by UA and their solution is to kill Instant Upgrade.

Another problem for UA

So for about $550 + 40,000 miles round trip, you could have an almost guaranteed upgrade from the cheapest non-basic economy fare to Polaris. That was truly exceptional value (the cheapest cash upgrade was usually around $1800 RT), and there was very little risk of being stuck in Economy Plus.
