Musician Royalties on Reissues

This is a question that popped into my head the other day and I imagine there would be a person or two on here who can satisfy my curiosity.

A few years back, they re-wrote the copyright laws in the EU. My understanding is that the portion of copyright law which applied to recorded works (as opposed to the written song, etc.) and which paid out to musicians who only PLAYED on a given recording was modified to only last for something like 35-40 years.

At the time this was being considered, Ian Anderson of Jethro Tull came out against it on the grounds that previous members of the band who were still living but no longer making music relied upon those royalties for income and would be robbed of it.

Fast forward, the change went through and we're now seeing a wave of reissues of earlier Jethro Tull material (wonderfully done, at that). My question is this: does that clock for this older material "reset" if it is remastered/remixed and re-released? I had a moment of idle curiosity as to whether Anderson had been pushing for catalog reissues to rectify lost income for those earlier incarnations of the band or if other bands are doing their own reissues for similar reasons.

I don't think it does. I think it starts from the date of original issue.

Date of the original recording, not a reissue, remix or remaster...because in all those cases they are still using the original recording.
