One of the primary reasons I bought Steam Deck was because it can suspend and resume a game mid-action. Ever since life kicked in low gear after 30s I can't really find time anymore to sit at TV and power on/load game anymore as it feels like a chore. What I figured is that I will just play in short bursts whenever I have free time, which means suspending game in a must feature. So far I haven't seen deck updating a game while I am playing it, but there was such event when I launched a game after it was doing updates and it got stuck on loading screen ( mad I/O on sdcard ). Had to pause update explicitly.
