Downgrade.
Honestly, don't take it. Apart from the inconsistent wording (no "after" or "when"), in my experience it is actually rare that an investigator moves more than once during their turn. Even if so, if this card is actually important to you you will pack two copies anyway.
The real downside, though, comes from the restriction: "During another investigator's turn"
This is HUGE, because combos with the following no longer work (a buddy using the card's effects you provided):
- Shortcut
- Carson Sinclair's ability
- Archive of Conduits
- Task Force
- Survival Instinct outside of their turn
- Prophesiae Profana
- The Stars Are Right using the action for movement in the mythos phase
Hate it.
