We are seeing two totally different things in that video. I see a player who is being very delicate on a bum, recovering leg.
Here's another video from that same workout, and he pretty clearly has a limp even when simply walking.

Yeah you (and others) are probably right that he's definitely treating it gingerly, and maybe isn't all that close to returning. I will say I don't see much of a limp, for whatever that's worth.
I was mostly focusing on how, in the second clip from that tweet, the first 40 seconds are him taking one legged shots, without pushing off on his right at all... but the last 20 seconds of it are him taking two legged shots, pushing off with
both legs. And I just saw that as a positive - that he's on a court, doing some basketball things, using his hurt leg. Maybe not nearly at game speeds, or ready for practice, but it's not like he has to rest it for another week before he even returns to basketball activities.
And if there's one thing last night underscored, it's how much we need KP back out there. Al Horford is probably overqualified as a 6th man / rotation big, but as a starting playoff starter, he's just giving up too much in too many circumstances. We can probably beat Cleveland as-is, but we're definitely not the death star without Porzingis.
