Now, why end the matching period? A utility-maximising donor ought to offer their 41 cents for as long as it takes—the utility of those 41 cents is always going to be higher than any 41-cent section of hedonistic spending (which is where the money is coming from). The answer lies partly in human psychology. A limited-time offer prompts action in a way that open-ended, time-independent offers do not. A progress bar prompts action too. It’s also partly from status: successfully completing campaigns like this raises the prestige of SingInst. Meeting the target before the specified end date raises the prestige of both SingInst and its donors.
These factors are convincing enough reasons to time-limit the matching offer, mostly because they solve the problem of the pledge not being fulfilled. Odd quirk of our brains to blame here.
The rational donor wouldn’t offer to match x for y time; they would simply offer to match x. So the donor would simply offer to match the first dollar and forty-one cents donated. There’s no risk of accidentally being required to donate more than you’d want to.
I thought humans did that a lot on financial markets (make an offer that potentially incurs an infinitely large obligation), in particular when they sell (“write”) certain option contracts?

don’t forget the simple explanation: It’s risky to offer to match infinite dollars.
