Shimano XT shifter question

Hi,
I'm repairing a friend's bike and can't tell if the shifter is okay or broken because...in 30 years of cycling I've never used this type of shifter. It's an XT rear shifter (see photo), and I'm guessing it's around 15 years old.

So, regarding the longer lever on the right, my question is:

When you push this lever to shift one gear, should the lever itself "spring back" to its original position? What I'm seeing is that the smaller lever on the left does spring back after each shift, but this lever seems to move one position and stay there. Then if you shift another gear, it moves forward a bit more and stays there. (In this sense, it's kind of like an old thumb shifter.) I guess I'm trying to find out if this is correct or if there's a broken spring mechanism here.

Any advice would really be appreciated.

It should spring back. Either broken spring or gummed up/rusted/worn mechanism. You could try spraying some silicone spray in there. It looks old, like 7 speed. If so, 7 speed replacements are quite cheap, though you'll have to choose something besides XT (unless you can find new old stock).

shoot it up with a degreaser then shoot it up with lube.

If that doesn't work, take off the cover. You'll see a pair of paws with springs. Those are usually gummed up. spray some degreaser and work the pawl back and forth until its no longer gummy and sticking. spray with lube and replace cover.

if that doesn't work, new shifter.

Well, I just realized I have one possible solution if I can't get this shifter working: I found some old DX shifters lying around that are absolutely identical in design. I must've taken these off my old mountain bike the moment I got it and put on thumb-shifters (as I certainly never used them), so it looks like I could just swap out the XT ones for these.
