Workflow concurrency limits?

For Workers & Pages, what is the name of the domain?

n/a

What is the issue or error you’re encountering

do workflows count as “active” against the concurrency limit when sleeping/waiting?

What steps have you taken to resolve the issue?

i was looking into implementing them for a project but took pause once i read the limits table:

the part that says “Concurrent Workflow instances (executions) per account” shows 25 for a free account, and 4000 for a paid account.

i read this as “you can only have 25 workflows running simultaneously on a free account.” is that how you read it? if my workflow is waiting for something to happen (using waitUntil or waitForEvent) does that count as an active instance? i am interested in running very long workflows (weeks to months in length) that will only use tiny amounts of compute here and there, but will be waiting around a lot. does this mean that i could only have 25 running at once?
