Nautilus Q Indicator shows wrong range

I recently noted that I hooked enemies with Nautilus Q even when they seemed out of range.

To test this:

1. disable Quickcast
2. face a terrain of choice (e.g. a tower)
3. walk away until the Q indicator shows that you're just (about 10-50 distance) not in range anymore
4. trigger Q
5. you will be hooked to that terrain

The Q indicator does not correspond to the actual range of Q (maybe due to more or less recent buff to his Q range)
