To have this redundancy provision is better than none at all?That question sums it up well. The answer obviously is ‘maybe, maybe not.
The question now becomes - Why create a redundancy which isn’t dependable?

Hopefully the obstruction will not clog the intake pipe before it gets to the filter?Then if the jam problem is the concern then install two filters with a switch valve to cause fuel to go to the clean filter.
That is always a possibility. Some boats were built with a screen on the intake. The screens do get clogged. But unlike the filter they are not in a place where yo can observe the clog. So you are guessing. It is the reason I remove screens and make the intake pipe an open source of fuel and any debris. Suck it up to the filter. The filter and any gunk can be seen and removed before it causes a serious problem.Hopefully the obstruction will not clog the intake pipe before it gets to the filter?
And if the obstruction is blocking at the intake and cannot go up to the filter?That is always a possibility. Some boats were built with a screen on the intake. The screens do get clogged.

It is wise to occasionally inspect the filter and the bowl for problems.
I'd believe the dirt in the tank is on the bottom except in choppy conditions. The shorter tube would be marginally shorter than the first, otherwise a partially emptied tank would render the short tube high and dry.; what may have plugged one tube may shortly plug the 2nd tube.
If it gets to that point there is really only one solution. You need to extract the intake and clear it as well as the hose line between the intake and the filter. You should also inspect the tank bottom and remove the obstructions.And if the obstruction is blocking at the intake and cannot go up to the filter?
