I was skeptical until I saw information confirming it.

It's not obvious that the frequency range used by computers recording on audiocassette would fit into that used by AM or FM radio transmission and reception equipment.

In other words, it's obvious that it would be possible on equipment specifically designed for it.

But I'm quite surprised that it worked without it (presumably) having been designed for. Or maybe they did pick a frequency ceiling compatible with commercial radio intentionally?

The cassette loading/saving on home computers had to be extremely failure tolerant so that it would work with low quality tapes and shitty recorders. I guess as a side effect this failure tolerance also made it work over radio.
