Yes, it must have changed. The only time I did this was a few months ago after Hawaiian canceled my inter-island flight from Maui to Honolulu. I ended up buying a walk-up fare on Go! so I wouldn't miss my international connection to Asia. That was my only option at the time. (And I wasn't particularly happy about it, but I was out of options.)
They apparently built a covered walkway between the remote end of the interisland terminal and the commuter terminal, so they no longer have to escort you across the tarmac.
Although, you still board and deplane on the tarmac using stairs at the commuter terminal. If you want to walk to the interisland terminal, you just enter the commuter terminal, don't exit security, and follow the signs. And there's signs in the interisland terminal directing you to the commuter terminal walkway.
