This just shows his ignorance towards dharmic faiths, Tony. The dharmic faiths of Hinduism, Buddhism, and Jainism have continuously been focused inward. There is no confusion at all. It's an empty accusation. 'All religions of the present day have fallen into superstitious practices'. Really? I would say adherents of those same religions would certainly disagree. How does one build unity and peace by being so very critical of other faiths? That certainly doesn't build bridges, it puts up walls. It does draw in all other critically minded folks looking for an excuse to say they're right and everyone else is wrong.In a talk about science and religion Abdul'baha has said this;
"....All religions of the present day have fallen into superstitious practices, out of harmony alike with the true principles of the teaching they represent and with the scientific discoveries of the time. Many religious leaders have grown to think that the importance of religion lies mainly in the adherence to a collection of certain dogmas and the practice of rites and ceremonies! Those whose souls they profess to cure are taught to believe likewise, and these cling tenaciously to the outward forms, confusing them with the inward truth."

Later in the same talk in your link he says this ... "Some worship the product of their own imagination: they make for themselves an imaginary God and adore this, when the creation of their finite minds cannot be the Infinite Mighty Maker of all things visible and invisible! Others worship the sun or trees, also stones! In past ages there were those who adored the sea, the clouds, and even clay!"
This is a pot shot at pagans and Hindus, more criticism where none is deserved. It shows that he clearly doesn't understand stuff from other paradigms. I know of no Hindu that worships stones. We worship Gods, and use images and murthies to channel it. It's a known inner science for eons ago, and works just as copper conducts electricity. So, with that analogy, he's mistaking the copper for the electricity. If a person ignorant of how electricity works saw the copper writing in a house he's think ... what stupidity is this, stringing a bunch of wires all about your house! And to think that if you touch them together some magic will happen! Absurd.
So I actually doubt that Abdul Bahai asked a single question of any Hindu or pagan. He just took a look, a brief cursory look and made a critical judgement based on his own false thinking based on what he got from his grandfather.
Frankly, it's disrespectful, if not downright insulting.
